The Department of Defense (DOD) is seeking proposals for the topic "DIRECT TO PHASE II: Fiber-Optic Filter Integration" as part of the SBIR 24.2 Annual program. The Navy branch is specifically interested in this topic. The objective is to design, fabricate, test, and integrate dichroic filters for use in digital avionics fiber-optic communication-link hardware and software. The goal is to reduce the time and complexity for a properly trained maintainer to detect and isolate a failure and affect repair. The use of optical fiber in military platforms is crucial for maintaining communication signal integrity. The research effort should focus on developing dichroic filters compatible with avionics fiber optics and models that include platform considerations for multimode fiber-optic links operating at different speeds. The research should also include the design and demonstration of prototypes for dichroic fiber use in avionics weapon replaceable assemblies, fiber-optic test equipment, adapters, and other optical interface circuitry. The project will have a Phase I feasibility stage, followed by Phase II for design, build, and testing of dichroic filters, and Phase III for finalizing the prototype design and transitioning to naval avionics use cases and platforms. The technology has potential applications in telecommunication systems, data centers, and campus networks. The solicitation is currently open, with a closing date of June 12, 2024.
