Abstract
A multiplexer/demultiplexer for routing different wavelength signals between a common pathway for conveying a plurality of the signals, and individual pathways for separately conveying the signals includes a reflective diffraction grating with reduced polarization sensitivity for dispersing the signals. The grating includes facets that are oriented for reducing efficiency variations within a transmission bandwidth and that are shaped for reducing differences between the diffraction efficiencies in two orthogonal directions of differentiation.
