Seminar: “Recent Results from both High Power and Broadly Tunable External Cavity Quantum Cascade Lasers”, Timothy Day


Friday, December 9, 2011 / 11:00am-12:00pm

Dr. Timothy Day

Chairman, CEO/CTO, Co-Founder of Daylight Solutions


Broad tunability in the mid-IR (~3-12 μm) is desirable for a number of applications. Daylight Solutions has built a number of External Cavity quantum cascade Lasers (ECqcL™) that maximize tuning range from the quantum cascade chip. As much as 525 cm-1 of pulsed and 121 cm-1 of cw, mode hop-free tuning has been obtained. Various mechanisms for the broadening of the gain of the QC chip are considered. High Power QCLs are also a major area of development producing platforms with up to 15 Watts optical output in the MWIR range.


Dr. Timothy Day is a cofounder of Daylight Solutions and serves as the CEO and CTO for the company. Daylight Solutions is an advanced manufacturer of molecular detection and imaging products, serving markets that include Industrial Process Control, Medical Diagnostics and Defense and Security using Mid IR lasers and sensor systems. Dr. Day concurrently serves as the executive manager for Daylight Defense, LLC, a wholly owned subsidiary of Daylight Solutions, established to serve the Defense and Security markets. While at Daylight Defense, he and his team have introduced several EO/IR products that serve the U.S. military in areas such as directed infrared countermeasures, stand-off detection of explosives, laser aiming/designating, combat ID, free-space secure communications and other applications. Dr. Day has over 20 years' experience in both technical and business management in the photonics industry. He has led engineering, research, product development, manufacturing, and marketing operations. He started his career as a cofounder of New Focus, where he served from 1990 through 2004. During his time at New Focus, he was involved in all aspects of the company’s history, concluding with his work on the sale of the company to Bookham Technology PLC for $338M. While at New Focus he also contributed to the raising of over $500M though public and private equity offerings. From 1990 to 2009, while at New Focus and Daylight Solutions, Dr. Day has developed extensive patent and product portfolios and transferred numerous products into production, both onshore and overseas.

Dr. Day holds both a BS and an MS in Physics from San Diego State University and a PhD in Electrical Engineering from Stanford University.
