Abstract
The Quantum Cascade Laser are valuable as the sources for the detection of large organic hydrocarbon molecules like the BTX compounds in the 12–16 µm region or for radio-astronomy as local oscillators in heterodyne detectors. In this work, long wavelength 16 µm quantum cascade lasers will be demonstrated at room temperature with high peak output power using a bound-to-continuum structure design. The structure was grown by gas sources molecular beam epitaxy and consist of a 45 period active region embedded in an optical waveguide. The devices were processed in 50 - to 70 - µm wide mesa using wet chemical etching and a SiO2 for passivation. Multimode emission with pulsed peak power up to 700 mW at 30°C and above 200 mW at 100°C will be presented. The emission spectrum consists of modes around 641 cm-1 (λ~15.6 µm) and around 602 cm-1 (λ~16.6 µm).
