摘要
A coherent receiver adapted to operate as an Optical Spectrum Analyzer (OSA) includes an optical front end adapted to receive an optical signal and to mix the optical signal with a local laser; a photodetector block coupled to the optical front end and adapted to receive an output of the optical front end and provide an output corresponding to spectral components of the optical signal; and a controller coupled to the optical front end and the photodetector block, wherein the controller is adapted to operate in an OSA mode to sweep the local laser across a portion of optical spectrum to perform an OSA measurement while not performing data demodulation.
