Aerius Photonics proposes to develop a high speed, high sensitivity focal plane array (FPA) assembly consisting of a low noise InGaAs photodiode array and a fast readout integrated circuit (ROIC). The FPA will be integrated into a laser vibrometer system and used for the detection of landmines and Improvised Explosive Devices (IEDs). In Phase II of the program, Aerius will focus on the design, fabrication and characterization of a FPA demonstration vehicle that will address the technical risks that affect the implementation of a full array. Aerius will work with its industry and government partners to test the assembled FPA at individual test facilities characterizing its optical and electrical performance. Testing of the FPA will demonstrate the applicability of this concept to laser vibrometer applications. The developed technology has applications in military, medical, and civilian markets. The technology can be used to remotely detect a human"s vital signs, as well as provide stand-off analysis of suicide bombers, as well as buried object detection.

Aerius Photonics proposes to develop a compact light-weight non-mechanical scanning LADAR for enhanced spacecraft survivability. This new technology will be used to detect and track natural and manmade physical threats to spacecraft. Such detection and tracking will allow the spacecraft to respond to a changing situation in order to improve its survivability. The technology will enable a wide field of view and be able to build 3D images of threats. In Phase I, Aerius will provide a system study to include the tradeoffs and operating ranges of several proposed techniques. Aerius will demonstrate scanning and ranging with a high gain receiver. Further tests will determine the radiation hardness for space operations of critical components. In Phase II, Aerius will design and deliver prototype devices, evaluate their performance, long term stress tests and radiation hardness tests.

ABSTRACT: The objective of this Phase II program is to develop a battery operated, friend or foe identification beacon (IFF Beacon) technology that is compact and can be worn on the warfighter as part of standard gear. The IFF beacon will project a high brightness beam across a hemisphere allowing standard pods on military aircraft (Blackhawk, Apache, etc.) to detect and identify friendly troops on the ground. In addition, the IFF beacon will have data transmission capability based on an IR pulsed laser that is fully integrated into the device. This laser based beacon technology will allow the warfighter to project his position for long ranges up to 15-20 km. The Aerius Photonics IFF beacon will be ruggedized for warfighter use and the hardware delivered to the customer at the end of the program. BENEFIT: The anticipated benefits of the technology are a reduction in SWaP and cost for a commercial grade system that is suitable for law enforcement, security, and search and rescue. A comparable device does not currently exist. The IFF laser beacon to be developed has many applications in defense and other markets. In addition to Department of Defense customers, the product would also be of use to police forces, Department of Homeland Security (DHS) and Coast Guard. During Phase II, Aerius will approach Prime DoD suppliers, as well as suppliers to police forces, DHS and the Coast Guard to establish sales and distribution channels addressing these markets. Early discussions with two Prime DoD suppliers, BAE Systems and Northrop Grumman have already taken place. Demand for the personnel tag devices market could grow to several thousand per month in a few years.

In Phase I, Aerius Photonics demonstrated Raman spectroscopy at 785 nm, 980 nm, and 1064 nm, with only 1064 nm-based excitation showing a reduction in fluorescence. In addition, Aerius Photonics and partner Ahura Scientific, demonstrated a breadboard version of an InGaAs-based Raman spectrometer to assess any engineering challenges. By the end of a Phase III, Aerius proposes to develop a handheld 1064 nm – based system that uses an extremely low-noise InGaAs array to not only reduce fluorescence, but maintain the SNR ratio achieved by 785 nm bases systems. The InGaAs arrays are based on Aerius’ low dark current InGaAs and low noise ROIC experience. This system will substantially reduce the fluorescence present in CCD-based systems, and unmask otherwise obscured spectra. At the end of a successful Phase II, we would deliver a prototype unit build around the FirstDefender core that is capable of identifying chemicals within seconds, and ready to be put into use very quickly.

ABSTRACT: Aerius Photonics proposes to develop a monolithic electronic-photonic silicon CMOS Focal Plane Array (FPA) to enable ultra-compact Imaging LADAR sensors. These miniature LADAR sensors would have far reaching impact on a number of DoD applications because of their dramatic reduction in cost, significantly smaller size, weight and power (SWaP) and their improved performance regarding sensitivity and frame rate. The CMOS FPA will integrate in one chip hundreds of photonic components and about one million transistors, making it one of the largest electronic-photonic integrated circuits ever fabricated. In Phase I, Aerius will design all the elements of the integrated chip and will test some individual components. This work will evaluate integration feasibility and reduce the risk for further development. Also in Phase I, Aerius will define the commercialization plan to guide action in Phase II and Phase III of the program. In Phase II, Aerius will fabricate a prototype FPA to demonstrate the significant functionality improvements targeted. The resulting high performance FPA prototypes will be provided to system integrators for incorporation into systems that benefit the mission of DoD and that will be transitioned into manufacturing in Phase III. BENEFIT: With the successful completion of this project, Aerius will have developed the technology to fabricate highly integrated electronic-photonic systems utilizing standard silicon CMOS technology. The first implementation of this technology will produce a miniature low cost LADAR system that will have a large impact on a vast range of defense and civilian systems such as: Unmanned Aerial Vehicle (UAV) navigation, target identification, weapon precision aiming, surveillance, recovery of injured warfighters, transportation, construction, manufacturing processes, traffic control and visual clues for blind people. The disruptive benefits brought about by this highly integrated FPA are enormous. Following the development of this miniature low cost LADAR, the technology can be applied to the development of other sensors such as detectors of biological and chemical agents and also for advanced communication systems.

Aerius Photonics proposes to develop a high-power coherently combined laser based on Vertical-Cavity Surface Emitting Laser (VCSEL) arrays. In Phase II, Aerius will develop the scalable technologies needed to fabricate a coherently combined VCSEL array, and at the end of Phase II, will demonstrate a coherently combined VCSEL array. A coherently combined diode laser is attractive for directly producing a high-quality coherent beam, thereby eliminating the requirement for mode conversion in solid-state lasers. This increases overall system efficiency and enables smaller, lower cost more mobile laser based systems. Such systems could be applied to directed energy weapons requiring 100 kWs of power. In Phase I, Aerius performed a feasibility study and proof of principle experiments demonstrating the feasibility of the proposed approach and the necessary scalable technologies for realizing a large form factor device were identified. In Phase II, these scalable technologies will be developed in depth towards building a coherently combined VCSEL array.

Aerius Photonics is proposing to develop high-power Vertical Cavity Surface Emitting Lasers (VCSELs) and arrays on 4” substrates with an integrated thermal management approach to improve the thermal performance on an entirely wafer-level manufacturing compatible process. This is critical as waste heat and wafer-scale manufacturing approaches are driving factors for performance and costs in a laser diode, especially diode pumped solid-state laser systems relevant to the US BMDS. The performance of the high-power diode laser is limited by the ability of the packaging to extract heat away from the laser’s active region, where the majority of the heat is generated. If the heat is not removed, the gain, and subsequently the output power and efficiency of the laser and entire system are decreased. In this proposal, Aerius will develop a wafer-scale compatible process on 4” substrates with improved thermal performance for high power VCSEL arrays. This approach will further improve the thermal performance and manufacturability of VCSEL technology and offer a 50% reduction in the laser diode heating by improving the waste heat transport and spreading from the semiconductor chip to the thermal management system.
