New accelerator applications within DOE require the use of high-power, high repetition rate, efficient solid state lasers. These lasers are pumped by diode lasers. Improving the efficiency of diode laser pumps will directly impact the overall efficiency and performance of solid state lasers. No high-efficiency technology for pump lasers in the 1.4-2.1 m wavelength range exists. Pump laser technology also has wide application areas in optical communications, materials processing, etc. In this program, Freedom Photonics will address the need for high efficiency pump lasers by leveraging its work on 1550nm high power lasers for communications and sensing. The overall project goal is to develop lasers >55% wall plug efficient at 1530 nm wavelength and >30% wall plug efficient at 1910 nm wavelength. The Phase I effort will focus on understanding the technical challenges and developing strategies to minimize their associated program risk. To accomplish this, feasibility of different approaches for improving pump laser efficiency will be studied. High-efficiency diode laser pumps are of importance for use with solid state fiber lasers, as well as in optical amplifier and repeater systems for fiber-optic communications, sensing, material processing, medicine, free-space optical communications. This program also promotes the development of a US workforce skilled in 21st century technologies such as the emerging field of photonics integration.

ABSTRACT: In this effort, Freedom Photonics will develop a high-sensitivity high-resolution coherent imaging system based on a Si avalanche photodiode (APD) array and corresponding bias and read-out electronics. This will be a monolithic APD and ROIC (readout-integrated-circuit) focal plane array (FPA) system. We start from a proven high-performance CMOS electronics backplane and build the photonics using the pre-existing CMOS steps. BENEFIT: Freedom Photonics will develop a Si CMOS APD and ROIC focal plane imaging system offering performance not yet available in the marketplace. The optical output of this imagining system will have unparalleled high-sensitivity and high-resolution, which will enable new Photonic solutions for the next generation of defense sensing and surveillance systems. This high performance imaging system will also have significant application opportunities in other markets. The key market segments and potential customers include optical Sensing, medical equipment, and medical imaging systems.

ABSTRACT:The overall technical objective for this effort is to develop a range of miniaturized integrated optical sources for alkali-atom based systems, including atomic clocks, inertial measurements systems, and cold-atom systems. These components should have a performance matching or exceeding todays state-of-art discrete components that are typically used in such systems. To achieve this goal, Freedom Photonics is proposing to develop an GaAs photonic integration platform that can be applied to Alkali-Atom systems and enable these future compact and ruggedized solutions. The initial target is to address Rubidium-atom systems in the 780-795nm range, however, the base platform to be developed is applicable over the full 600nm to 1,000nm range.BENEFIT:The development of compact photonic integrated sources will allow a wide range of alkali based systems to be realized with significantly reduced Size, Weight and Power (SWaP) compared to todays systems based on discrete optical components, which is of fundamental importance to many defense and commercial applications. The main application areas for this photonic integration technology are: atomic clocks, pump sources for Rubidium Ring Lasers, Cold-Atom Systems and Diode Pumped Solid State Lasers (DPSSL).

In this program, Freedom Photonics will develop and build a robust, low C-SWaP laser source with improved performance over current technology, to be incorporated into improved FOS interrogator systems. The laser will be 40nm continuously tunable around C-band, with fast sweep rate. The laser interrogator module to be developed will be based on our advanced monolithic, fast-tunable laser and receiver technology, leading to ultra-low SWaP with smaller FOS laser interrogator module, two orders of magnitude smaller than existing technology, and interrogator mass less than 100 grams. The configuration will be rugged, compatible with fuel, fuel vapor, shock, and vibration.
