Low-Cost-By-Design Widely Tunable Mid-Wave Infrared Surface Emitting Lasers Navy SBIR FY2015.1 Sol No.: Navy SBIR FY2015.1 Topic No.: N151-023 Topic Title: Low-Cost-By-Design Widely Tunable Mid-Wave Infrared Surface Emitting Lasers Proposal No.: N151-023-0790 Firm: Nour, LLC 1500 Sheridan RD UNIT 8A Wilmette, Illinois 60091 Contact: Steven Slivken Phone: (847) 467-4093 Abstract: The functionality of widely tunable sampled grating mid-infrared lasers will be enhanced through the development of surface emission. This technology provides fast, non-mechanical tuning in the mid-infrared spectral range. The proposed research will investigate the feasibility of integrating a 45 degree facet with the sampled grating distributed feedback quantum cascade laser in order to simultaneously achieve high power, surface emission, and wide tunability. A novel integrated optics approach is also proposed for coherent power scaling of this technology. Benefits: The proposed widely tunable surface emitting quantum cascade laser integrates monolithic tuning of wavelength with a monolithic beam deflector for surface emission. This solution is non-mechanical in nature, and can take advantage of the cost savings associated with wafer-scale production of surface-emitting devices. Such a device is highly attractive for standoff spectroscopy, free-space communication and infrared countermeasure systems, in which cost, size, and weight are prime factors. Upon completion of the project, an inexpensive, compact, and lightweight mid-infrared tunable laser source will be available for military and industrial applications. Return
