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.
Claims16
An optical multiplexing device comprising:
- a first light band-reflect filter that receives an incident beam, reflects a first reflected beam of a first light wavelength band, and transmits a first transmitted beam comprising light wavelengths other than the first light wavelength band;
- a first receiver that receives the first reflected beam from the first light band-reflect filter;
- a second light band-reflect filter that receives the first transmitted beam from the first light band-reflect filter, reflects a second reflected beam of a second light wavelength band, and transmits a second transmitted beam comprising light wavelengths other than the second light wavelength band;
- and
- a second receiver that receives the second reflected light wavelength band from the second light band-reflect filter.
An optical multiplexing device comprising at least one light-extraction module intercepting a light beam, each light-extraction module comprising
- 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;
- and
- a receiver that receives the reflected beam from the light band-reflect filter.
