Code Division Multiple Access (CDMA) with MMI Mineral-Organic Circuits
Abstract
The optical fiber, which offers a large bandwidth (about five TeraHertz per telecommunication window), can be fully used only if the techniques of multiple access are sufficiently effective. Our technology based on an organic-inorganic material offers a solution for the realization of the coupling and the decoupling of transmitted channels : in addition to the multiplexer with division by wavelength (WDM) based on multimode interference couplers, we present here a system of multiple access with division by code (CDMA) using multimode interference couplers as well.
