Spectrometer On A Chip: An InP-based Grating Demultiplexer For WDM Applications At 1.5μm


We report an InP-based grating spectrometer for WDM systems operating in the 1.5µm fiber band. The spectrometer resolves more than 50 wavelength demultiplexed channels at 1mm spacing with a 3Λ channel width and at least 19dB isolation between outputs. The spectrometer operation is almost independent of the state of the input polarization.
