In this paper, we propose multiple-channel OSNR monitoring using integrated planar lightwave circuit (PLC) and fast Fourier transform (FFT) techniques with a single detector. We experimentally demonstrated a 4-channel OSNR monitoring and accurately measured OSNR up to 20 dB. Optical signal to noise ratio (OSNR) monitoring is one of the essential optical performance monitoring functions in wavelength-division-multiplexing (WDM) systems. Different OSNR monitoring methods have been reported. The arrayed-waveguide grating (AWG) with a detector array has been widely used to monitor OSNR of WDM channels.
