Integrated performance monitoring PLC circuit for WDM system

An integrated performance monitoring PLC circuit based on a double-resolution-AWG-based power monitoring circuit concatenating with a tunable periodic notch filter is proposed and demonstrated. It achieves wavelength, power and high dynamic range OSNR monitoring functionalities on a single chip.
