Optical code-division multiple access (O-CDMA) interconnects and telecommunication networks based on temporally accessed spectral multiplexing (TASM)

A novel optical interconnect architecture based on temporally accessed spectral multiplexing (TASM) technology is presented. The use of TASM optical interconnects will be demonstrated in multiple access telecommunication applications. TASM technology builds on optical code- division multiple access concepts with promise of low cost implementation of Terabit/second optical networks. The use of TASM technology to enhance wavelength division multiplexing in optical communication systems will be discussed. The working principles and design of TASM system architectures will be presented with emphasis on the key functional component - the TASM encoder.

Code-division-multiplexing-compatible coding and decoding of directly driven DFB laser bit streams

Optical implementation of code-multiplexing is heavily contingent upon compatibility of encoding devices with standard laser sources. We demonstrate encoding and decoding of RZ signals generated at 2.5 Gbps by direct-driving of a semiconductor DFB laser.
