Reconfigurable multi-level phase shift keying encoder-decoder for all-optical networks

By M.R. Mokhtar, M. Ibsen, P.C. Teh and D.J. Richardson

Abstract

We demonstrate the application of a uniform Bragg grating as a dynamically reconfigurable phase encoder-decoder for optical systems. Precise discrete phase modulation between chips is obtained simply by heating segments along the grating with fine resistive wires. Its reliability to generate and recognize various phase code sequences is demonstrated in a 16-chip 20-Gchip/s quaternary phase-shift keying coherent optical code-division multiple access experiment. The bit-error-rate response is also included to highlight its performance
