Title: Wavelength division multiplexing/demultiplexing devices using polymer lenses

Abstract: An improved wavelength division multiplexing device is disclosed. The improved wavelength division multiplexing device has a diffraction grating for combining a plurality of monochromatic optical beams into a multiplexed, polychromatic optical beam. The improvement in the improved wavelength division multiplexing device is the use of a polymer collimating/focusing lens for collimating the plurality of monochromatic optical beams traveling along a first direction to the diffraction grating, and for focusing the multiplexed, polychromatic optical beam traveling along a second direction from the diffraction grating, wherein the second direction being substantially opposite the first direction.
