摘要	A coaxial transmitter optical subassembly (TOSA) including a side-by-side laser diode and monitor photodiode package, consistent with embodiments of the present disclosure, may be used in an optical transceiver for transmitting an optical signal at a channel wavelength. In an embodiment, the coaxial TOSA includes a laser sub-mount coupled to a mounting region defined by a body of the coaxial TOSA. The laser sub-mount includes a monitor photodiode disposed adjacent to a side of a laser diode such that a sensor region of the monitor photodiode is disposed within, or in close proximity to, a light cone emitted by a light emitting surface of the laser diode. The monitor photodiode is thus configured to directly receive a portion of emitted channel wavelengths from the laser diode for monitoring purposes.
其他摘要	根据本公开的实施例的包括并排激光二极管和监视器光电二极管封装的同轴发射器光学子组件（TOSA）可以用在光学收发器中，用于以信道波长发射光学信号。在一个实施例中，同轴TOSA包括耦合到由同轴TOSA的主体限定的安装区域的激光器子安装座。激光器子底座包括邻近激光二极管的一侧设置的监控光电二极管，使得监控光电二极管的传感器区域设置在由激光二极管的发光表面发射的光锥内或紧邻光锥。。因此，监控光电二极管被配置为直接从激光二极管接收一部分发射的通道波长以用于监控目的。
