Epitaxial microcavity devices, such as surface emitting lasers [1,2], vertical cavity modulators [3,4], and all-optical bistable microresonators [5,6], are currently subject to a lot of interest for their potential application in photonic switching. Due to their small active volume and their optical access perpendicular to the surface, they can be integrated as two-dimensional arrays, with a device density of 106 devices/cm2 or larger. Such arrays of all-optical bistable devices could be useful as opto-optical modulators, wavelength converters, optical logic gates, or fast access digital optical memories. |
