摘要	Photonic integrated circuits (PICs), also referred to as opto-electronic integrated circuits(OEICs), and more particularly to a PIC in the form of an optical receiver PIC or RxPICchip and an optical transmitter PIC (TxPIC) are employed in an optical transport network.Integrated on the RxPIC chip, starting at the input end which is coupled to receivemultiplexed optical data signals from an optical transport network is an optical amplifier,an optical demultiplexer, and a plurality of on-chip photodiodes (PDs) each to receive ademultiplexed data signal from the AWG DEMUX for optical-to-electrical signalconversion. The optical input amplifier may be an on-chip gain clamped semiconductoroptical amplifier (GC-SOA) or an off-chip fiber amplifier. The optical input amplifiermay be optional if the channel signal demultiplexer provides for minimal insertion losswhich is optimum with a properly designed arrayed waveguide grating (AWG)demultiplexer.
其他摘要	光学集成电路（PIC），也称为光电集成电路（OEIC），更具体地说是光接收器PIC或RxPICchip形式的PIC和光发送器PIC（TxPIC），用于光传输在RxPIC芯片上集成，从输入端开始耦合以接收来自光传输网络的多路复用光数据信号，是光放大器，光解复用器和多个片上光电二极管（PD），每个都接收到多路复用。来自AWG DEMUX的数据信号用于光电转换信号。光输入放大器可以是片上增益钳位半导体光放大器（GC-SOA）或片外光纤放大器。如果通道信号多路分解器提供最小的插入损耗，则光输入放大器可以是可选的，这对于适当设计的阵列波导光栅（AWG）多路分解器是最佳的。
