About this opportunity
Office of the Secretary of Defense SBIR topic — under DoW SBIR 2026 BAA (Solicitation 26.BZ, Release 4) — Accepting submissions 2026-07-22 to 2026-08-19. Objective: To design, develop, and demonstrate a large étendue, high spectral resolution Asymmetric Spatial Heterodyne (ASH) interferometer optimized for quantum sensing, quantum communication support, and dual-use remote sensing applications. Description: Quantum communication systems, quantum-enhanced LiDAR, and quantum sensing platforms share a critical and unmet instrumentation need: a spectrometer capable of simultaneously achieving large étendue (high optical throughput) and high spectral resolution. In satellite-based and ground-based quantum key distribution (QKD), ground station receivers must collect single photons from spatiall...
