Distributed Tunable Quantum Cascade Laser Array Navy SBIR FY2012.1 Sol No.: Navy SBIR FY2012.1 Topic No.: N121-032 Topic Title: Distributed Tunable Quantum Cascade Laser Array Proposal No.: N121-032-0014 Firm: MP Technologies, LLC 1500 Sheridan RD, SUITE 8A Wilmette, Illinois 60091 Contact: Steven Slivken Phone: (847) 491-7208 Abstract: Infrared countermeasure and standoff chemical detection applications require a light source with high power output, good beam quality, and a wide tuning range. There are a limited number of viable mid-infrared (3-5 micron wavelength) solutions that can provide these features in a compact and power scalable architecture. In this proposal, a single chip solution is given which promises high power output (multi-Watt), a compact, rugged nature, and continuous frequency tuning (no-mode hops) over a wide range (>400 inverse-centimeters). The basic technology relies on new high power quantum cascade lasers combined with industry proven distributed feedback and integrated optics technologies. Benefits: This compact and high power tunable mid-infrared laser source will provide the tunability necessary for a wide range of standoff chemical sensing/ imaging applications in the mid-infrared. This will allow a single sensor system to monitor multiple distant points in series while allowing personnel to keep a safe distance from potential chemical threats, such as explosives or toxic chemicals. Chemical imaging at a distance will also be possible when paired with a suitable infrared camera technology, such as one based on Type-II superlattices. The high output power and wide tuning range will also allow this single source to be a drop-in replacement for multiple narrowband infrared countermeasure sources in band IV. Return
