Quantum Cascade Lasers Manufacturing 10X Cost Reduction

Pendar Technologies proposes to develop novel manufacturing processes to reduce the cost of high-power mid-wave infrared quantum cascade laser (QCL) sources by a factor of at least 10x without compromising laser performance, i.e. power, beam quality and wall-plug efficiency. Our approach will leverage recent advances made by Pendar in bandstructure engineering, laser cavity design and thermal management at the chip and the package level. The planned developments also include taking advantage of (1) access to high-capacity multi-pocket commercial reactors capable of growing QCLs on 4 inch wafers (2) high-yield buried heterostructure processes developed by Pendar to enable high power QCL bars and (3) the availability of automated tools such as die bonders to achieve high-yield, high-throughput packaging at low-costs.
