Abstract

Summary form only given. We have incorporated a vertical microcavity into an all-optical serial-to-parallel converter based on surface-emitted second-harmonic generation (SESHG). By resonating at the second-harmonic wavelength, the conversion efficiency is improved sufficiently to allow bit error rate (BER) measurements on an SESHG demultiplexer for the first time. This optical time-division demultiplexer has the important advantage that a single device can recover all of the multiplexed channels in a single operation. The SESHG structure is comprised of a quasi-phase-matched (QPM) waveguide imbedded between two distributed Bragg reflectors (DBRs), which form a microcavity resonator.
