A semiconductor optoelectronic device includes at least one cavity and one
multilayered interference reflector. The cavity is designed preferably to
possess properties of an antiwaveguiding cavity, where no optical modes
propagate in the lateral plane. The existing optical modes are the modes
propagating in the vertical direction or in a direction tilted to the
vertical direction at an angle smaller than the angle of the total
internal reflection at the semiconductor/air interface. This design
reduces the influence of parasitic optical modes and improves
characteristics of optoelectronic devices including vertical cavity
surface emitting lasers, tilted cavity lasers emitting through the top
surface or the substrate, vertical or tilted cavity resonant
photodetectors, vertical or tilted cavity resonant optical amplifiers,
and light-emitting diodes.
