摘要	An optical transmitter includes an external cavity laser array formed in a PLC, a trench-based detector array and an AWG. The external cavity laser is formed using an array of substantially similar laser gain blocks and an array of gratings formed in waveguides connected to the gain blocks. Each grating defines the output wavelength for its corresponding external cavity laser. Each detector of the detector array includes a coupler to cause a portion of a corresponding laser output signal of the laser array to propagate through a first sidewall of a trench and reflect off a second sidewall of the trench to a photodetector. In one embodiment, the photodetector outputs a signal indicative of the power level of the reflected signal, which a controller uses to control the laser array to equalize the power of the laser output signals.
其他摘要	光发射器包括形成在PLC中的外腔激光器阵列，基于沟槽的探测器阵列和AWG。使用基本上类似的激光增益块阵列和在连接到增益块的波导中形成的光栅阵列形成外腔激光器。每个光栅定义其相应外腔激光器的输出波长。探测器阵列的每个探测器包括耦合器，以使激光器阵列的相应激光输出信号的一部分传播通过沟槽的第一侧壁并从沟槽的第二侧壁反射到光电探测器。在一个实施例中，光电检测器输出指示反射信号的功率电平的信号，控制器使用该信号控制激光器阵列以均衡激光输出信号的功率。
