Abstract: Disclosed are the method and system to derive the wavelength/frequency information covering wide wavelength or frequency range. Its practical applications include both fixed wavelength optical signal and wide bandwidth tunable or non-tunable optical signal, where the wavelength/frequency information is necessary for optical signal calibration, control, and monitoring, optical communications, and data processing. The approach has a “self-compensation” feature which is preferred to improve the accuracy of the extracted wavelength or frequency information even though there are components in the system having strong wavelength or frequency dependence in the wide wavelength or frequency range. The method is generic which can be realized in free space, fiber, or photonic integrated circuit (PIC).
