Abstract
An optical multiplexing device has at least one light-extraction module intercepting a light beam. Each light-extraction module includes a light band-reflect filter that receives the light beam, reflects a reflected beam of an extracted light wavelength band, and transmits the light beam except for the extracted light wavelength band. A light receiver receives the reflected beam from the light band-reflect filter. A number of the light-extraction modules, each having a light band-reflect filter operable with a different wavelength, serially process the light beam to extract each desired wavelength.
