Multi-Wavelength Optical Code-Division-Multiplexing Based on Passive, Linear, Unitary Filters

摘要

The bulk results form the research can be found in Mr. Cedric Lam's Ph.D. dissertation, Multiple-wavelength Optical Coded-Division-Multiple-Access Communication Systems, published by UCLA in 1999. The main principle of optical CDMA is similar to radio CDMA. Instead of transmitting signals using only the necessary bandwidth, the signal energy is spread over a frequency spectrum, much broader than required to carry to information, by an encoding operation.
