AdTech Photonics specializes in mid-infrared semiconductor lasers powered by quantum cascade laser technology. The company maintains in-house capabilities across epitaxy, wafer processing, device fabrication, and reliability screening to support fast prototyping and scalable production. It offers laser chips and packaged modules in several formats for OEM use, with mid-IR wavelengths down to about 4.6 μm to serve sensing and spectroscopy applications.

OEMs can engage AdTech Photonics at the chip, subassembly, or turnkey module level, with application engineering support and reliable lead times backed by rigorous lab evaluation. Headquartered in City of Industry, California, the company was founded in 2001 as AdTech Optics, later expanding into QCLs and evolving into AdTech Photonics to reflect its broader photonics manufacturing scope. The firm operates as a small- to mid-sized player in the semiconductor sector and collaborates with universities and programs such as the NSF MIRTHE initiative.
