Double-metal waveguide 19mum quantum cascade lasers grown by metal organic vapour phase epitaxy

Quantum cascade lasers designed to emit at 19mum grown by metal organic vapour phase epitaxy are demonstrated to operate in pulsed mode up to 170K. The structures are processed into a double-metal waveguide that enhances mode confinement while minimising waveguide losses. The performance of the mate...

Summary:Quantum cascade lasers designed to emit at 19mum grown by metal organic vapour phase epitaxy are demonstrated to operate in pulsed mode up to 170K. The structures are processed into a double-metal waveguide that enhances mode confinement while minimising waveguide losses. The performance of the material grown at rates of 6 and 1A/s is compared. The devices constitute the longest-wavelength quantum cascade lasers grown by metal organic vapour phase epitaxy to date.
