摘要	A photonic integrated circuit (PIC) includes a semiconductor substrate with a main bus waveguide disposed within the substrate. Two or more ring lasers are disposed within the substrate and are optically coupled to the main bus waveguide. The ring lasers have a wavelength control mechanism allowing change of a lasers emitted wavelength. A wavelength selective filter is optically coupled to the bus waveguide. A control circuit is electronically coupled to each wavelength control mechanism, and the wavelength selective filter. The control circuit in conjunction with the selective filter allows monitoring of a ring laser's wavelength on the main bus waveguide. Based on a determined wavelength, the control circuit may change a ring laser wavelength to a desired wavelength to achieve a desired wavelength spacing for each of the ring lasers. The PIC may be integrated as a coarse wave-length division multiplexing (CWDM) transmit module.
其他摘要	光子集成电路（PIC）包括半导体基板，主总线波导位于基板内。两个或多个环形激光器设置在基板内，并且光学耦合到主总线波导。环形激光器具有允许改变激光器发射波长的波长控制机制。波长选择滤光器光学耦合到总线波导。控制电路电耦合至每个波长控制机构和波长选择滤波器。控制电路与选择性滤波器配合使用，可以监视主总线波导上的环形激光器的波长。基于确定的波长，控制电路可以将环形激光器的波长改变为期望的波长，以针对每个环形激光器实现期望的波长间隔。 PIC可以集成为粗波分复用（CWDM）发送模块。
