高达 40 Gb/s 的超高速集成光源已经开发出来。 InGaAsP MQW 集成光源由多量子阱 (MQW) 电吸收 (EA) 调制器和分布式反馈 (DFB) 激光器组成。在优化集成调制器的结构后，该器件采用单模光纤（SMF）封装在紧凑的模块中。当 DFB 激光器注入恒定电流时，集成 MQW 电吸收调制器由 40 Gb/s 电 NRZ 信号驱动。在来自调制器的调制光中观察到清晰张开的眼图。此外，在误码率 (BER) 性能方面，实验证实了 10/sup -9/ 时接收器灵敏度为 -27.2 dBm。使用新型光源模块还可以以 40 GHz 的重复频率生成高分辨率光学短脉冲。
A very high-speed integrated light source up to 40 Gb/s has been developed. The InGaAsP MQW integrated light source consists of an multiple-quantum-well (MQW) electroabsorption (EA) modulator and a distributed-feedback (DFB) laser. After optimizing the structure of the integrated modulator, the device is packaged in a compact module with a single-mode fiber (SMF). While the DFB laser is injected with a constant current, the integrated MQW electroabsorption modulator is driven with a 40-Gb/s electrical NRZ signal. A clearly-open eye diagram is observed in the modulated light from the modulator. Further, a receiver sensitivity of -27.2 dBm at 10/sup -9/ is experimentally confirmed in bit-error-rate (BER) performance. Highly resolved optical short pulse is also generated at a repetition rate of 40 GHz using the new light-source module.
