Abstract
A diffraction grating for optical communication is disclosed. The diffraction grating includes a substrate and a reflective material adjacent the substrate, wherein one or more input optical signals incident the reflective material is diffracted into one or more output optical signals over a wavelength range of at least approximately 30 nm, within which the diffraction grating is substantially polarization insensitive.
