Abstract
A monolithic InP-based grating spectrometer for use in wavelength-division multiplexed systems at 1.5 μm is reported. The spectrometer uses a single etched reflective focusing diffraction grating and resolves > 50 channels at 1nm spacing with a ~0.3 nm channel width and at least 19 dB channel isolation. Operation is essentially of the state of the input polarisation.Keywords
