MWIR lasers using Type II quantum well active regions on InP substrates

ABSTRACT: We propose to develop modeling and initial concept feasibility demonstration for MWIR lasers that span the 2.4-4 um wavelength span. The laser active region design is based on a novel quantum well design that is grown on InP substrates. The laser will leverage our team's recent advances and demonstrations in quantum well design be use Princeton Lightwave's laser fabrication platform. During Phase I we will perform detailed electro-optic and quantum phenomena modeling with experimental feasibility demonstration of the concept. BENEFIT: There is a need for solid state lasers that can cover the 2.4-4 um spectral range for applications such as free space optical communications (deep-space Earth based communications), molecular spectroscopy (laser induced breakdown spectroscopy), and infra-red countermeasures for military and commercial air-platform protection.
