Interband cascade laser emitting at λ=3.75 μm in continuous wave above room temperature
Abstract
We report a five-stage interband cascade laser that operates at λ =3.75μm in cw mode up to a maximum temperature of 319K. With gold electroplating, epitaxial-side-up mounting, and one facet coated for high reflectivity, a 3mm×9.2μm ridge emits over 10mW of cw power at 300K.
