Selectively oxidized vertical cavity lasers emitting near 1300 nm using
InGaAsN quantum wells are reported for the first time which operate continuous
wave below, at and above room temperature. The lasers employ two n-type Al0.94Ga0.06As/GaAs
distributed Bragg reflectors each with a selectively oxidized current aperture
adjacent to the active region, and the top output mirror contains a tunnel junction
to inject holes into the active region. Continuous wave single mode lasing is observed
up to 55 C.
