    Abstract: Improved wavelength division multiplexing/demultiplexing devices are disclosed. In the case of an improved wavelength division multiplexing devic e having a diffraction grating for combining a plurality of monochromatic optical beams into a multiplexed, polychromatic optical beam, the improvemen t comprises employing a plurality of patterned optical input components corresponding to the plurality of monochromatic optical beams, wherein each of the plurality of patterned optical input components introduces a first patterned phase delay into a corresponding one of the plurality of monochromatic optical beams. The improvement also comprises employing a patterned optical output component for introducing a second patterned phase delay into the multiplexed, polychromatic optical beam, wherein the first patterned phase delay and the second patterned phase delay are added so as t o reshape the passband of the improved wavelength division multiplexing device .

    Abstract: A wavelength division multiplexer/demultiplexer (WDM) for use in an optical network and in an optical performance monitor that minimizes increases in insertion losses over temperature variations. The WDM has a structure for holding at least one optical component. A diffraction grating assembly having a substrate is held in relation to the at least one optical component by the structure. A lens assembly having a focal length is held in relation to the at least one optical component. The coefficient of thermal expansion of the lens assembly and structure are approximately equal. The lens assembly is constructed from a material chosen to minimize its variance in focal length over temperature. The grating assembly has an angular dispersion that changes with temperature and the product of the focal length and angular dispersion remains constant over temperature. The WDM further comprises a prism having a change in index of refraction with temperature that is approximately equal to a negative of a coefficent of thermal expansion of the substrate. The substrate has a coefficient of thermal expansion approximately equal to a negative of a coefficient of thermal expansion of air.
