Three categories of multiwatt, coherent laser designs are discussed. The designs are single-mode waveguides suitable for output powers in the order of 200 mW, single-mode operation of multimode lasers, which are suitable for operation between 0.5 and 1.0 W, and the monolithically integrated master-oscillator power amplifier (M-MOPA) designs that have demonstrated 4.5 W of spectrally coherent output power and more than 0.8 W of single-lobe diffraction-limited output power in a technology that is scalable to even higher output powers. Laser-diode design architectures and the unique properties of semiconductor materials are reviewed 相似文献

The personal access communication system (PACS) radio interface is the leading low-tier candidate for standardization in North America. This radio interface was originally conceived to serve pedestrian and fixed-distribution applications; there has been significant recent interest in extending this technology into high-mobility environments. In such environments, rapid channel variations significantly degrade the performance of the preselection diversity scheme proposed for use in PACS handsets. The effects of time-delay spread on the PACS radio link was also included in our investigation. It is found that a received signal strength indicator (RSSI) with a short measurement length can better cope with high fading rates than can a quality measure in a preselection diversity system, although a quality measure has better performance than RSSI at low speeds in the presence of time-delay spread. In the preselection diversity scheme, using short-measurement RSSI provides relatively good performance in both low- and high-mobility environments. However, its performance degrades rapidly for RMS delay spreads larger than about 9% of a symbol time. Postselection diversity using two complete receiver chains is more robust than preselection diversity, both to high fading rates and to delay spread. Postselection diversity is relatively insensitive to changes in the fading rate and can tolerate an RMS delay spread up to 12.5% of a symbol time 相似文献

采用恒流源技术设计了1种适合于DC-DC开关电源的模拟加法器。基于CSMC 0.5 μm混合标准CMOS工艺对所设计电路进行了仿真验证。在3 V电源电压条件下,瞬态仿真结果显示模拟加法器输出VA为参考电压Vref与输入信号VA1的加权。当输入信号VA1从0~1.2 V变化时,模拟加法器的输出电压VA与VA1成线性关系,且VA与VA1的差值恒为一常数。当温度在0~110 ℃范围内变化时,模拟加法器的输出VA偏差仅为1.18 mV。仿真结果显示:该模拟加法器具有非常好的性能特性,适用于DC-DC开关电源。 相似文献
