Abstract :
Laser diodes based on 4ML InAs/3ML GaSb/1ML InSb/3ML GaSb short-period superlattices (SPSLs) for emission in the 3-3.5 mum wavelength range have been investigated. Lasing is demonstrated up to 300-K in pulsed conditions and up to 200-K under continuous wave operation. Laser emission is centred at 3.3 mum, a technologically very important wavelength. The results demonstrate the potential of these new active zones for mid-IR laser diodes.
