Vertical waveguiding in etched semiconductor nonlinear microcavities

Abstract

Vertical microcavity devices, due to their specific geometry, are naturally adapted to the implementation of parallel architectures for information processing, taking advantage of the high interconnection capability of optics. However the density of active devices that can be operated simultaneously in a two-dimensional array format is generally limited by thermal dissipation, and significant efforts are currently devoted to increasing the efficiency and reducing the power consumption of individual devices.
