Long wavelength (λ > 13 μm) quantum cascade laser based on diagonal transition and three-phonon-resonance design
An InP-based quantum cascade laser structure emitting at a wavelength of 13.6 μm is proposed and demonstrated. The active region is based on a diagonal transition and three-phonon-resonance design. A 5 mm long, 30 μm wide high-reflection coated device with a double channel ridge waveguide structure...
