Company History

In 2005, AdTech Optics, Inc. advanced beyond traditional semiconductor laser technologies, committing itself aggressively to the emerging field of quantum cascade lasers (QCLs). In 2008, the company spun off its photodiode and laser-diode chip division into a new entity, D-Tech Optoelectronics, Inc., to allow AdTech to focus its resources exclusively on mid-infrared lasers and system integration. In 2012 (federal registration 2018), AdTech Optics rebranded/recapitalised as AdTech Photonics, Inc., continuing the heritage of laser design, manufacturing and innovation, employing approximately 35 staff and achieving ISO 9001:2008 certification in 2015. At the City of Industry, California facility, the company maintains full in-house capability to design, engineer and manufacture semiconductor laser devices, with a particular emphasis on QCLs for defense, environmental and medical applications.

Xiaojun Wang,
Director of Chip Development

Xiaojun brings to AdTech an industrial and research experience in semiconductor optoelectronic materials and devices that spans 20 years. Currently he is the Director of Chip Development at AdTech, managing the MOCVD material growth and device fabrication for high performance Mid-Infrared Quantum Cascade Lasers. He joined AdTech since 2003, and focused on the developments of Near-Infrared high power laser diodes and DFB/EML for telecom/data communications applications during his first three years. Prior to AdTech, Xiaojun was with Nortel Networks from 2000 to 2002 as a senior device engineer, developing the 1310nm single mode pump laser and MEMS/VCSEL based C/L band high power tunable laser. From 1998 till 2000, he was a Research Scientist in University of Maryland Baltimore County, working on InP-based optical components for communication applications. He conducted research on 980nm and 808nm high power lasers, and GaN LED on GaAs in the Institute of Semiconductors, Chinese Academy of Sciences (ISCAS), during his Ph.D. thesis study and post-doctoral period from 1992 to 1997.

Xiaojun holds a Ph. D. degree in Semiconductor Device Physics from XiaMen University (on a joint program with ISCAS), China. He is a member of IEEE, SPIE, and served as PI/co-PIs for projects supported by various agencies. He has authored and co-authored more than 80 peer-reviewed publications.
