1.55-/spl mu/m, InP-lattice-matched VCSELs operating at RT under CW

We demonstrate the first room temperature, continuous-wave (CW) operation of a 1.55-/spl mu/m InGaAs vertical-cavity surface emitting laser (VCSEL) that is completely lattice-matched to InP and produced in one epitaxial growth. The structure employed intracavity contacts with an air-gap aperture. The threshold current and threshold current density were 6.2mA and 1.97kA/cm/sup 2/, respectively, at 200 C with a 20-/spl mu/m-diameter current aperture.
