Abstract
We demonstrate a lattice-matched vertical-cavity surface-emitting laser operating continuous wave up to The laser employs AlAsSb-based mirrors, which provide high reflectivity and lattice matching to InP. The poor electrical and thermal conductivity of these mirrors is circumvented by utilizing an InP double-intracavity contacted structure. Benefits of the intracavity contacts are addressed by comparing the characteristics with the alternative contact scheme where current is injected through the Sb-based mirrors. Current and optical confinement is provided by an undercut aperture. The device shows a threshold current of a differential efficiency of 23%, and a maximum output power of over 1 mW at
