摘要	An optical receiver photonic integrated circuit (RxPIC) comprises a semiconductor monolithic chip having an input to receive from an optical transmission link a combined channel signal originating from an optical transmitter source and comprising a plurality of channel signals having different wavelengths forming a wavelength grid. An optical decombiner is integrated in the chip and optically coupled to the input to receive the multiplexed channel signal and provide a decombined individual channel signal on an output waveguide of a plurality of such output waveguides provided from the optical decombiner. A plurality of photodetectors are also integrated in the chip and each photodetector is optically coupled to one of the output waveguides to receive a decombined channel signal and convert the channel signal to an electrical signal. A controller is coupled to receive a portion of the converted signals to determine at least one performance property of the signals and provide service channel signal as feedback about that property via the semiconductor monolithic chip to the optical transmitter source. The controller is coupled to an integrated optical service channel (OSC) on the chip that has a light source which is modulated by the service channel signal. The light source may be integrated on the chip. The optical service channel (OSC) is coupled as an input to the decombiner for transport off the chip to optical transmitter source. If there is an optical amplifier at the input of the chip, the service channel signai will be amplified by that amplifier. Such an optical amplifier may be an off-chip rare earth doped amplifier or an on-chip semiconductor optical amplifier.
