Abstract
Data are presented on half-wave cavity vertical cavity surface emitting lasers using both oxide confinement and high contrast upper and lower distributed Bragg reflectors. Six pairs of MgF/ZnSe distributed Bragg reflectors make up the top mirror and 11 pairs of AlxOy/GaAs DBRs make up the lower DBR. The oxide layer thickness in the AlxOy/GaAs DBRs is less than a quarter-wavelength in order to reduce strain on the quantum well active region. The lasing characteristics of device sizes ranging from 7 micrometer to 1 micrometer are analyzed through spectral data, far field radiation patterns and lasing threshold.
