Emerging wavelength-division multiplexing (WDM) technology finds application in increasing system capacity and in microwave signal processing. Photonic microwave mixing for WDM systems using a microwave oscillator has been proposed. In this approach, WDM channels carrying radio frequency signals are simultaneously downconverted to intermediate frequencies by a fiber-based local oscillator, and detected by a low-speed detector array.
