An all-epitaxial GaInAsN vertical-cavity surface-emitting laser for room-te
mperature (RT) emission at 1.3 mum was developed by solid-source molecular
beam epitaxy using a plasmasource for nitrogen activation. RT photopumped o
peration is demonstrated at a wavelength of 1283 nm, Stimulated emission wa
s observed up to a record high temperature of 143 degreesC, resulting in an
emission wavelength of 1294 nm.
