Progress in Interband Cascade Lasers: from edge emitting lasers to VCSELs
Abstract
Mid-infrared lasers are crucial devices to enable optical spectroscopy in this spectral region of strategic importance for molecular sensing. In this presentation, we will review our recent progress in mid-infrared sources based on interband cascade active regions for operation in the L-band (wavelength of ~3.4µm) and in particular towards the demonstration of VCSELs, the most promising laser embodiment for energy-efficient portable tunable sources.
