Type-I laser diodes:
Brolis Semiconductors develops mid-infrared laser diodes based on type-I optical transition on GaSb technology platform. Type-I optical transition results when an electron and a hole recombines across the effective bandgap of the quantum well in the active semiconductor material.
Type-I transition advantages:
- High gain
- Low operating voltage
- Wavelength reproducibility
- CW operation at RT
Laser diodes based on type-I transition combine advantages of highest optical gain and very low voltage drop ( i.e. Brolis laser diodes have operating voltages < 1 V compared to ~15 V quantum cascade lasers QCLs and ~3-5 V interband cascade lasers ICLs) resulting in extremely low input powers and uncooled room-temperature operation in continuous-wave mode.
