Blue lasing at room temperature in an optically pumped lattice-matched AlInN/GaN VCSEL structure
Blue lasing at room temperature in an optically pumped lattice-matched AlInN/GaN VCSEL structure
Laser action with low threshold average pump power density (~50 W - cm-2 ) at room temperature is reported for a crack-free planar vertical cavity surface emitting laser (VCSEL) structure based on a bottom lattice-matched AllnN/GaN distributed Bragg reflector (DBR) and a top dielectric DBR. The cavity region, formed by n- and p-type GaN layers surrounding only three InGaN/GaN quantum wells, corresponds to a typical active region suitable for an electrically driven VCSEL. In addition to low threshold, a spontaneous emission coupling factor beta ~ 2 x 10-10 is derived for this ready-to-be-processed laser structure.

Abstract
Laser action with low threshold average pump power density (~50 W - cm-2 ) at room temperature is reported for a crack-free planar vertical cavity surface emitting laser (VCSEL) structure based on a bottom lattice-matched AllnN/GaN distributed Bragg reflector (DBR) and a top dielectric DBR. The cavity region, formed by n- and p-type GaN layers surrounding only three InGaN/GaN quantum wells, corresponds to a typical active region suitable for an electrically driven VCSEL. In addition to low threshold, a spontaneous emission coupling factor beta ~ 2 x 10-10 is derived for this ready-to-be-processed laser structure.
