OBJECTIVE: Develop radiation hardened mid-wave infrared (MWIR) sensors for strategic applications.
DESCRIPTION: The performance requirements for MWIR image sensors used in strategic navigation applications continue to become more stringent, necessitating continued innovation for image sensor technologies. Examples of existing research for MWIR imaging sensor technology can be found in the referenced articles [Ref. 1-3]. The applications are also expanding, leading to a need for larger pixel counts and smaller pixels in MWIR imagers. Conventional MWIR sensors have large pixels making large arrays prohibitively expensive.
Commercial applications for MWIR are far reaching, with some examples being stress identification in materials, human tracking/security and automotive and machine industries. This technology would enable devices to be used at higher temperatures in a wider range of environments.
In terms of idealities, these MWIR sensors should have low-noise readout preferably with minimal cooling (e.g., High Operational Temperature (HOT) sensor), have high-density (< = 8 Ķm) pixel pitch, be radiation-hard at strategic levels, have low power consumption, and be able to be fabricated using foundry processes.
PHASE I: Perform a design and performance modeling study aimed at MWIR sensors with improved performance for strategic sensors as compared to the current state-of-the-art. Assess performance and environmental sensitivity of parameters including responsivity, speed, noise, and defective pixels. Consider all aspects of fabrication and justify the feasibility/practicality of the approach. A goal of quantum efficiency greater than 40% and operability greater than 95% of pixels is desired. Propose, in a Phase II plan, a specific device design for fabrication based upon this analysis.
PHASE II: Fabricate and characterize a small number of prototype MWIR sensors (Up to Qty: 3). Characterization using EMVA1288 standard, shall comprise various parameters including responsivity, speed, noise, and defective pixels in relevant radiation environments. The prototypes should be delivered by the end of Phase II.
PHASE III DUAL USE APPLICATIONS: Continue development to lead to production of MWIR sensors. Production level applications would be highly sought for military seeker applications, strategic needs as well as commercial applications. An image sensor that can meet the stringent performance requirements of strategic instrumentation is likely to bring value to many existing commercial applications. MWIR can be used in the commercial sector for a variety of reasons including stress identification in materials, human tracking/security, and automotive and machine industries. This technology would enable devices to be used at higher temperatures in a wider range of environments.

** TOPIC NOTICE **
The Navy Topic above is an "unofficial" copy from the overall DoD 21.2 SBIR BAA. Please see the official DoD Topic website at rt.cto.mil/rtl-small-business-resources/sbir-sttr/ for any updates.
The DoD issued its 21.2 SBIR BAA pre-release on April 21, which opens to receive proposals on May 19, 2021, and closes June 17, 2021 (12:00pm edt).
Direct Contact with Topic Authors: During the pre-release period (April 21 thru May 18, 2021) proposing firms have an opportunity to directly contact the Technical Point of Contact (TPOC) to ask technical questions about the specific BAA topic. Once DoD begins accepting proposals on May 19, 2021 no further direct contact between proposers and topic authors is allowed unless the Topic Author is responding to a question submitted during the Pre-release period.
SITIS Q&A System: After the pre-release period, proposers may submit written questions through SITIS (SBIR/STTR Interactive Topic Information System) at www.dodsbirsttr.mil/topics-app/, login and follow instructions. In SITIS, the questioner and respondent remain anonymous but all questions and answers are posted for general viewing.
Note: Questions should be limited to specific information related to improving the understanding of a particular topicís requirements. Proposing firms may not ask for advice or guidance on solution approach and you may not submit additional material to the topic author. If information provided during an exchange with the topic author is deemed necessary for proposal preparation, that information will be made available to all parties through SITIS. After the pre-release period, questions must be asked through the SITIS on-line system.
