Wavelength-Division Multiplexing Device As Optical Multiplexer-Demultiplexer
Tech ID: 22075 / UC Case 2004-257-0
Brief Description
A novel Wavelength-Division Multiplexer device to interleave multiple signals into a multiplexed, multi-channel optical laser signal.
Background
Wavelength-division multiplexing (WDM) systems place several different wavelengths of laser radiation into a single optical fiber (multiplexing) at the transmitter, and spatially separate the wavelengths at the receiver (demultiplexing). Most wavelength-division multiplexing schemes are either expensive, bulky, or suffer from poor insertion loss characteristics.
.Description
Researchers at the University of California, Santa Barbara have developed a novel Wavelength-Division Multiplexer device to interleave multiple signals into a multiplexed, multi-channel optical laser signal. The device can also work in the reverse direction to separate (demultiplex) an optical laser signal containing several different wavelengths into separate signals with corresponding channels.
Advantages
- Compact
- Improved insertion loss characteristics
Applications
- Wavelength-division multiplexing and demultiplexing techniques
- Optical devices for multiplexing and demultiplexing several different wavelengths of laser radiation
- Wavelength routing and channel dropping applications
