Abstract :
An ultrafast single-wavelength optically time-division multiplexed (OTDM) link is described. The link exploits a unique integrated, all-optical serial-to-parallel (S/P) converter based on second-harmonic generation that demultiplexes multiple high-speed optical channels with a single operation. The link is composed of five major components: (1) a high-repetition-rate picosecond-pulse source; (2) a planar waveguide multiplexer that incorporates electroabsorption modulators with integral spot-size converters (SSCs); (3) a dispersion-managed (DM) short-pulse fiber channel; (4) a quasi-phase-matched, resonant-cavity-enhanced AlGaAs waveguide designed for surface-emitted second-harmonic generation (SESHG); and (5) a 775-nm receiver optimized for return-to-zero (RZ) operation. We describe our recent advances with resonant cavity enhancement of the all-optical demultiplexer and the first bit error rate (BER) measurements for this demultiplexing scheme.
