Abstract

External cavity quantum cascade lasers (ECqcL™) are now a commercial reality. This technology allows for the advances in quantum cascade (QC) materials to be realized. Significant advances in higher powers, broader tuning, higher efficiency, broader center wavelength coverage and higher operating temperatures have been made in the ECqcL™ commercial platform. This platform is ideally suited to address applications in the Scientific and OEM sensor markets ranging from gas sensing of complex matrices to condensed phase detection. By providing broad wavelength tunability throughout the mid-IR, these sources have the ability to obtain broadband absorption spectra and analyze complex matrices with high sensitivity and specificity. Integrated sensor embodiments also provide fast acquisition speed while providing turn-key operation. This paper will report on recent progress of the commercial ECqcL™ platform. State-of-the-art performance in terms of wavelength coverage, tuning range and power levels will be discussed.

 

About our speaker

Dr. Timothy Day was one of the four founders of New Focus, Inc. As Chief Technology Officer (CTO) and Senior Vice President, he developed numerous photonics products and was instrumental in growing the business to over $20M/year in revenue, as a private company, selling into photonics research markets. He developed an extensive patent and product portfolio and helped transition the company for a successful public offering in May 2000. Dr. Day contributed to the raising of over $500M through private equity offerings and 2 public offerings. As CTO of the public company, Dr. Day developed technologies and products that grew New Focus to over $40M/qtr in revenue with over 2000 employees in 8 sites worldwide. Dr. Day subsequently helped drive the divestiture of non-core businesses, raising $62M, and eventually sold the company in 2004 to Bookham Technology PLC. Dr. Day has extensive technical knowledge and experience, and is considered an expert in the field of photonics. Dr. Day holds both a B.S. and an M.S. in Physics from San Diego State University and a Ph.D. in Electrical Engineering from Stanford University.
