Low Cost/Low Phase Noise Laser Source for Interferometer Hydrophone Sensor Array Navy SBIR FY2010.3 Sol No.: Navy SBIR FY2010.3 Topic No.: N103-219 Topic Title: Low Cost/Low Phase Noise Laser Source for Interferometer Hydrophone Sensor Array Proposal No.: N103-219-0712 Firm: Princeton Lightwave, Inc. 2555 Route 130 South, Suite 1 Cranbury, New Jersey 08512-3509 Contact: Ketan Patel Phone: (609) 495-2552 Web Site: www.princetonlightwave.com Abstract: A low cost, low noise, narrow linewidth, high power laser is proposed using semiconductor laser and scalable manufacturing technologies. The underlying technology is an external cavity laser leveraging existing materials and processes developed for the telecommunication industry. The target application is for fiber optic sensors for detection of signal in the sub-MHz and sub-kHz frequency range. A primary example of such sensors are fiber-optic acoustic hyrdrophones. Benefits: Potential commercial applications is as an optical source for ultra sensitivity fiber optic sensors, such as biomedical instrumentation, industrial monitoring, environmental/seismic monitoring and motion detection, by acoustic microphones and hydrophones. The primary benefit of the development effort is to improve on cost (by 2-10x) and manufacturability of lasers, as compared to existing commercial laser sources, while maintain comparable laser performance.
