We have successfully fabricated post-type InGaN VCSEL structures and observed their room temperature oscillation at 399 nm under optical excitation. The nitride structures were grown by atmospheric-pressure metalorganic chemical vapor deposition (MOCVD). X-ray diffraction (XRD) was employed to chara

The effects of carrier leakage and gain-cavity alignment on the temperature dependence of the threshold current (I th ) in visible vertical cavity surface emitting lasers (VCSELs) are investigated. In order to assess the two effects and the degree to which they couple we have performed pressure and
Calculations of the frequency noise spectra and of the coherence functions between the electrical and the optical noises for a single-mode packaged vertical surface emitting laser (VCSEL) are reported.A rate-equation model for an index guided VCSEL is used, implemented with the electrical noise mode
