Abstract
The features of photonic crystal vertical cavity surface-emitting lasers (VCSEL) that exhibits improved optical confinement and resultant scaling of laser properties were described. In the photonic crystal VCSEL, electrical confinement is provided by an oxide layer that is larger than the optical aperture defined by the defect diameter present in the photonic crystal lattice. In the case of the selectively-oxidized VCSEL, the optical and electrical apertures possessed the same dimension due to the insulating and low refractive index properties of the oxide layers. The use of photonic crystal confinement, in which the etched holes and light propagation are parallel, provides a means for reducing the modal volume of microcavity lasers.
