Quantum Cascade Lasers Manufacturing 10X Cost Reduction

TransWave Photonics proposes an innovative quantum cascade laser manufacturing approach to reducing quantum cascade laser cost more than 10 times by increasing yield and manufacturing throughput without the need of manufacturing infrastructure up-scaling. Addressing the slow growth rate of the quantum cascade laser active region, overgrowth for buried-heterostructure fabrication, and devices packaging, we provide all-wafer-level manufacturing protocols that can considerably reduce the current manufacturing cost quantum cascade laser devices. Based on our estimation, successful demonstration of our approach should provide at least 10.15 times cost reduction, resulting in less than $100 for a single quantum cascade laser emitting at 4.6 µm with output power level over 1 W under continuous wave mode at room temperature, offering <$100/W end product cost to the current quantum cascade laser market.
