Double-metal waveguide lambda [sime] 19 mu m quantum cascade lasers grown by metal organic vapour phase epitaxy

Quantum cascade lasers designed to emit at lambda [NOT approximately equal to ]19 mu m grown by metal organic vapour phase epitaxy are demonstrated to operate in pulsed mode up to 170 K. The structures are processed into a double-metal waveguide, that enhances mode confinement, while minimising wave...

Summary:Quantum cascade lasers designed to emit at lambda [NOT approximately equal to ]19 mu m grown by metal organic vapour phase epitaxy are demonstrated to operate in pulsed mode up to 170 K. 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 1 Aa/s is compared. The devices constitute, the longest-wavelength quantum cascade lasers grown by metal organic vapour phase epitaxy to date.
