高速率并行光发射模块的研制

介绍了有关并行光发射模块设计与制作的最新进展，制作并测试了12信道并行光发射模块，单信道传输速率大于2．5Gbit／s（最高可达3Gbit／s），12信道并行总传输速率为30Gbit／s。模块采用波长为850nm的垂直腔面发射激光器（VCSEL）作光源，激光器与驱动电路芯片直接用Au丝连接，输出光束直接耦合进入12信道的光纤阵列中，在单信道8mA的工作电流下，可以测到最高为3Gbit／s的清晰眼图。

Manufacture of High Speed Parallel Optical Transmission Modules

We reported on our recent progress in the design and fabrication of a parallel optical transmitter.The 12-channel parallel optical transmitter with each channel's data rate up to 3 Gbit/s was designed and measured.An 850 nm vertical cavity surface emitting laser(VCSEL) array was adopted as the light source,and the VCSEL chip was directly wire bonded to a 12-channel driver IC.The outputs of the VCSEL array were directly coupled into a 12-channel fiber array.The eye diagram at 3 Gbit/s was achieved with the optical output more than 1 mW at operating current 8 mA.
