<p>An improved wavelength division multiplexing device (WDM) is disclosed. The wavelength division multiplexing device has a diffraction grating (18) for combining a plurality of monochromatic optical beams into a multiplexed, polychromatic optical beam. The WDM uses one or more polymer collimating/focusing lenses. The WDM uses one or more polymer collimating/focusing lenses. The VDM is connected to optical input (12a-12d) and output (22) fibers via the connecting ports (14, 20) secured to coupling devices. The grating works in a near-littrow configuration.</p> |
