Notes:
We report a two-dimensional grating spectrometer implemented in an InP/InGaAsP/InP planar waveguide for use in the low-loss 1.5 μm wavelength fiber band. The spectrometer uses a single vertical-walled focusing reflection grating to disperse 78 channels, spaced at 1 nm intervals, with diffraction-limited resolution (∼0.3 nm) and a high channel isolation ((approximately-greater-than)19 dB). The spectrometer may be used such that it is insensitive to the state of the input polarization.
