An optical multiplexing device spatially disburses collimated light from a fiber optic waveguide into individual wavelength bands, or multiplexes such individual wavelength bands to a common fiber optic waveguide or other destination. The optical multiplexing device has application for dense...http://www.google.ca/patents/US5786915?utm_source=gb-gplus-sharePatent US5786915 - Optical multiplexing device
