Technology for simultaneous demultiplexing of subrate tributaries is described and applied to 320-Gb/s return-to-zero input. The parametric architecture is scalable with respect to processed input rate and relies on cascaded all-optical multicasting and subrate sampling. Processing of 320-Gb/s input was achieved by creating eight channel copies, followed by a 20-THz-wide parametric gate. Multicasting was based on a self-seeded two-pump broadband fiber-optic parametric amplifier. The architecture was used to demonstrate error-free parallel demultiplexing of eight 320-Gb/s tributary channels at 40 Gb/s. 相似文献

We demonstrate excellent all-optical demultiplexing of 40-Gb/s base-rate channels out of 160- and 320-Gb/s single polarization optical time-division-multiplexed data streams. The demultiplexer utilizes a semiconductor optical amplifier and an optical filter placed at the amplifier output. The center wavelength of the filter is blue-shifted from the wavelength of the clock signal, so that ultrafast chirp dynamics can be employed for optical switching. Error-free demultiplexing was achieved at very low optical switch powers: 3.5 mW (160-Gb/s data), 6.3 mW (320-Gb/s data), and 0.09 mW (40-GHz clock). The proposed demultiplexer has a simple structure and allows monolithic integration. 相似文献

A monolithic integrated transimpedance amplifier for the receiver in a 40-Gb/s optical-fiber TDM system has been fabricated in an InP-based HBT technology. Despite its high gain (transimpedance of 2 kΩ in the limiting mode, 10 kΩ in the linear mode) the complete amplifier was realized on a single chip. Clear output eye diagrams were measured up to 43 Gb/s under realistic driving conditions. The voltage swing of 0.6 Vpp at the differential 50 Ω output does not change within the demanded input dynamic range of 6 dB. At the upper input current level even 48 Gb/s were achieved. The power consumption is approximately 600 mW at a single supply voltage of -5.5 V 相似文献

Short return-to-zero pulses (/spl sim/2 ps) are generated at bit rates of 40, 80, and 160 Gb/s using a fiber-optical parametric amplifier. The performance of the parametric pulse source is evaluated both back-to-back and in a 110-km transmission link. A receiver sensitivity of -33 dBm back-to-back was achieved after demultiplexing from 160 to 10 Gb/s. The power penalty at 160 Gb/s due to 110-km transmission was less than 2 dB. Very short pulses (0.5 ps) were also achieved when using the parametric amplifier as a compressor. 相似文献

We propose an asymmetrical interferometer to compensate the pattern effect in semiconductor optical amplifier (SOA) as an inline amplifier in dense wavelength-division-multiplexing (DWDM) system. Experiments are demonstrated with a commercial integrated Mach-Zehnder interferometer (MZI)-SOA. The experiments showed that in a 16×10-Gb/s DWDM system, the power penalty induced by the SOA decreased from 6.8 to 0.9 dB by the interference at 1 mW input power, and the input power dynamic range of the SOA was efficiently extended 相似文献

This paper presents a fully electrical 40-Gb/s time-division-multiplexing (TDM) system prototype transmitter and receiver. The input and output interface of the prototype are four-channel 10-Gb/s signals. The prototype can be mounted on a 300-mm-height rack and offers stable 40-Gb/s operation with a single power supply voltage. InP high-electron mobility transistor (HEMT) digital IC's perform 40-Gb/s multiplexing/demultiplexing and regeneration. In the receiver prototype, unitraveling-carrier photodiode (UTC-PD) generates 1 Vpp output and directly drives the InP HEMT decision circuit (DEC) without any need for an electronic amplifier. A clock recovery circuit recovers a 40-GHz clock with jitter of 220 fspp from a 40-Gb/s nonreturn-to-zero (NRZ) optical input. The tolerable dispersion range of the prototype within a 1-dB penalty from the receiver sensitivity at zero-dispersion is as wide as 95 ps/nm, and the clock phase margin is wider than 70° over almost all the tolerable dispersion range. A 100-km-long transmission experiment was performed using the prototype. A high receiver sensitivity [-25.1 dBm for NRZ (27-1) pseudorandom binary sequence (PRBS)] was obtained after the transmission. The 40-Gb/s regeneration of the InP DEC suppressed the deviation in sensitivity among output channels to only 0.3 dB. In addition, four-channel 40-Gb/s wavelength-division-multiplexing (WDM) transmission was successfully performed 相似文献

We have developed a hybrid-integrated symmetric Mach-Zehnder all-optical switch and evaluated the demultiplexing of 168-Gb/s data pulses at a repetition rate of 10 GHz with this switch. A compact, stable device was realized by assembling semiconductor optical amplifiers as nonlinear waveguides on a planar lightwave circuit in a self-aligned manner. A 6.0-ps switching window needed for 168-Gb/s demultiplexing was provided by the push-pull operation of the symmetric Mach-Zehnder all-optical switch. Demultiplexed signal light showed a high extinction ratio of better than 18 dB. Error-free demultiplexing with a bit error rate of 10-11 was achieved 相似文献

A transimpedance amplifier, designed in a digital 120-nm CMOS technology, used as preamplifier for optical burst-mode receivers in passive optical networks is presented. A wide optical input power range of 27 dB can be handled with a variable transimpedance without stability problems by varying the open-loop gain by a factor of 115. Noise and stability analysis of the optical receiver are presented. Sensitivities of - 31.3 dBm at 622 Mb/s and - 28.6 dBm at 1.25 Gb/s with a bit error ratio of 10/sup -10/ and a pseudorandom bit stream of 2/sup 31/-1 are achieved with a power consumption of 88.5 mW. 相似文献

Widely tunable wavelength converter using a double-ring fiber laser with a semiconductor optical amplifier 总被引:1,自引:0,他引:1
Widely tunable wavelength conversion has been demonstrated using broad-band orthogonal-pump four-wave mixing in a semiconductor optical amplifier placed at the intersection of two fiber ring lasers. The all-optical wavelength converter operates without using any external pump source. A 3-dB conversion-range over 40 nm is obtained. The measured power penalty is 1.5 dB for a 2.5-Gb/s converted signal at 10/sup -9/ bit error rate. 相似文献

A complementary metal-oxide-semiconductor (CMOS) monolithically integrated photoreceiver is presented. The circuit was fabricated in a 130-nm unmodified CMOS process flow on 2-/spl mu/m-thick silicon-on-insulator substrates. The receiver operated at 8 Gb/s with 2-dBm average input optical power and a bit error rate of less than 10/sup -9/. The integrated lateral p-i-n photodetector was simultaneously realized with the amplifier and had a responsivity of 0.07 A/W at 850 nm. The measured receiver sensitivities at 5, 3.125, 2, and 1 Gb/s, were -10.9, -15.4, -16.5, and -19 dBm, respectively. A 3-V single-supply operation was possible at bit rates up to 3.125 Gb/s. The transimpedance gain of the receivers was in the range 53.4-31 dB/spl Omega/. The circuit dissipated total power between 10 mW and 35 mW, depending on the design. 相似文献

A chip set composed of a laser-diode driver (LDD) and an optical receiver (RCV), which incorporates a full 2D (reshape, regenerate) function, has been developed by using silicon bipolar technology for a four-channel 5-Gb/s parallel optical transceiver. An electro-optical mixed design on SPICE of the LDD and the LD is accomplished by describing the rate equations of the LD as an electrical circuit. This design accommodates easy connectivity of the LDD chip to the LD in the optical transmitter module without the need for adjustment of the optical waveform. A pseudobalanced transimpedance amplifier (TIA) and feedforward automatic decision threshold control (ATC) in the RCV minimize the number of off-chip bypass capacitors, eliminate the need for any off-chip coupling capacitors, and keep crosstalk less than -50 dB and low cutoff frequency less than 80 kHz. A prototype parallel optical transmitter module and a prototype receiver module, based on the chip set, demonstrated asynchronous four-channel 5-Gb/s operation. The chip set has a throughput of 20 Gb/s with a power dissipation of 1.3 W at a 3.3-V supply 相似文献

A 10-Gb/s optical single sideband (OSSB) system using alternate mark inversion return-to-zero and ideal electrical precompensation of dispersion is optimized numerically by means of an optical dispersion compensator at the receiver side. The transmission regime observed in the optimized system resembles the pseudolinear regime previously described for systems with bit rates of 40 Gb/s and above. Considering multichannel transmission, the OSSB system has a Q -factor penalty of 2 dB compared to an intensity modulated optical double sideband system with optimized optical dispersion map. 相似文献

A nonlinear model for a travelling-wave semiconductor optical amplifier has been used to determine eye closure degradations for 2.4 and 10 Gb/s NRZ/RZ lightwave systems due to gain saturation effects in the optical amplifier. At 10 Gb/s, with a carrier lifetime of 300 ps, the results indicate that the penalty is less than 1 dB for both NRZ and RZ systems provided that the ratio of the input power (P in ) to the saturation output power (P sat) is less than -17 dB. The NRZ system penalty is slightly larger than the RZ penalty when P in/P sat is larger than -17 dB. For example, with P in/P sat=-10 dB, the NRZ system penalty is about 2.8 dB versus 2 dB for the RZ system. The system penalty at 2.4 Gb/s is slightly less than that at 10 Gb/s. At P in/P sat=-10 dB, the NRZ system penalty is about 2.5 dB versus 1.5 dB for RZ 相似文献

High-speed logic operation of an output interface circuit for a single-flux-quantum (SFQ) system was demonstrated at a data rate of 5 Gb/s. Using NEC's 2.5-kA/cm/sup 2/ Nb junction process, we designed, fabricated, and tested the interface circuit consisting of a 2-b SFQ demultiplexer and two Josephson latching drivers. We verified the proper operation of the demultiplexer. The interface can convert 5-Gb/s SFQ-pulse data into two-channel 2.5-Gb/s return-to-zero data with an amplitude of approximately 6 mV. 相似文献
