Abstract
We have incorporated a vertical microcavity into an all-optical serial-to-parallel converter1 based on surface-emitted second-harmonic generation (SESHG).2 By resonating at the second-harmonic wavelength, the conversion efficiency is improved sufficiently to allow biterror 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.
