A novel InP monolithically integrated coherent transmitter has been designed, fabricated and tested. The photonic integrated circuit consists of a distributed Bragg reflector laser and a modified nested Mach-Zehnder modulator having tunable input power splitters. Back-to-back coherent transmission for PDM-QPSK signals is reported up to 10 Gbaud (40 Gb/s) using the integrated laser and up to 32Gbaud (128 Gb/s) using an external low phase noise laser.
一种新型的磷化铟单片集成相干发射器已被设计、制造和测试。该光子集成电路由一个分布式布拉格反射器激光器和一个具有可调输入功率分配器的改进型嵌套马赫-曾德尔调制器组成。使用集成激光器，报道了高达10波特（40Gb/s）的偏振复用四相相移键控（PDM-QPSK）信号的背对背相干传输，使用外部低相位噪声激光器则高达32波特（128Gb/s）。
