Temperature Desensitised Uncooled Multi-Quantum Well Lasers

Summary Researchers from the University of Surrey have developed a novel design of multi-quantum well (MQW) laser that possesses a reduced thermal sensitivity over a wide temperature range. Bandgap engineering alone is used to improve the thermal stability of threshold current and slope efficiency compared to traditional techniques. The patent-pending...
