Terahertz electroluminescence from AlSb/GaSb quantum cascade laser structure

AlSb/GaSb quantum cascade laser structure was fabricated and evaluated. Design frequency of oscillation was 2.6 THz. A terahertz electroluminescence at 4K was measured by using gallium doped germanium photodetector. With an increase of injection current, above certain threshold, an abrupt increase o...

Zusammenfassung:AlSb/GaSb quantum cascade laser structure was fabricated and evaluated. Design frequency of oscillation was 2.6 THz. A terahertz electroluminescence at 4K was measured by using gallium doped germanium photodetector. With an increase of injection current, above certain threshold, an abrupt increase of luminescence has been observed.
