摘要	A pump laser package may include an input fiber to send signal light on a first optical path inside a package, a source to send pump light on a second optical path inside the package, and an output fiber on a third optical path inside the package. The pump laser package may include a WDM filter inside the package to receive the signal light on the first optical path and send the signal light on the third optical path, and receive the pump light on the second optical path and send the pump light on the third optical path. The pump laser package may include an isolator inside the package to transmit the signal light in a first direction, and block the signal light in a second direction, or a photo-diode to receive a portion of the signal light sent on a fourth optical path.
其他摘要	泵浦激光器封装可包括：输入光纤，用于在封装内的第一光路上发送信号光;源，用于在封装内的第二光路上发送泵浦光;以及输出光纤，位于封装内的第三光路上。泵浦激光器封装可以在封装内部包括WDM滤波器，以在第一光路上接收信号光并在第三光路上发送信号光，并在第二光路上接收泵浦光并在泵浦灯上发送泵浦光。第三光路。泵浦激光器封装可以包括封装内部的隔离器以沿第一方向传输信号光，并沿第二方向阻挡信号光，或者包括光电二极管以接收在第四光路上发送的信号光的一部分。。
