The Department of Defense (DOD) is seeking proposals for the topic of "Chip scale resonant sensors" as part of their SBIR 24.2 Annual solicitation. The research topic falls under the Air Force branch and is focused on integrated sensing and cyber, microelectronics, quantum science, and advanced materials. The objective is to design, fabricate, and characterize optical sensors with reduced dimensions that can operate with high sensitivity and spectral selectivity using resonant photonic devices. The sensors will be compatible with standard semiconductor nanofabrication platforms. The project will involve designing the sensor, selecting optimal materials, evaluating operational capabilities, and developing a plan for fabrication. In Phase II, a grating-based sensor processing line will be built, and experimental verification of the proposed materials will be conducted. The designs will be refined and optimized, and multiple fabrication rounds will be performed. In Phase III, the goal is to partner with a DoD prime contractor to develop a fabrication process compatible with their current or planned infrared (IR) sensors. The project duration is not specified, but the open date for proposals is May 15, 2024, and the close date is June 12, 2024. More details can be found on the grants.gov website.
