Abstract: Indium arsenide (InAs)-based quantum cascade lasers (QCLs) operating close to 25 µm are reported. Thick n-doped InAs cladding layers were used for optical confinement. Fabry–Perot lasers exhibited a threshold current density as low as 1.1… read more here.

Abstract: We briefly review the features of interband cascade lasers (ICLs) and discuss rationales for using an InAs-based plasmon waveguide configuration for extending efficient operation of ICLs to long wavelengths. We then present our recent progress… read more here.
