Abstract

The authors detail an initial experimental demonstration of (de)coding of optical sequences coded in the two-dimensions of phase and wavelength through a pseudolocal oscillator. Narrow pulses at 1 Gb/s originating from a supercontinuum (SC) fiber source with a specific frequency variation across their temporal width were, in addition, phase coded producing hybrid optical sequences. Successful decoding of the sequences using a pseudolocal oscillator in tandem with a coupler and balanced detector (coherent decoding) was accomplished. This approach to code formation allows access to a larger family of codes, potentially permitting more flexible network implementations based on optical code division principles.
