Abstract :
Summary form only given. We have previously proposed an ultrafast all-optical demultiplexer based on surface-emitted second-harmonic generation (SESHG) for optically time-division multiplexed (OTDM) communications. This scheme is advantageous in that it provides a serial-to-parallel functionality, allowing all of the multiplexed channels to be recovered with a single device. Here we report a new structure which virtually eliminates linear and two-photon absorption and thereby allows the efficient use of a vertical cavity resonant at the second-harmonic. The combination of reduced loss and the resonant cavity enhancement is expected to yield efficiencies suitable for 160 Gb/s operation.
