Apex Microdevices LLC

Apex Microdevices LLC, a minority-owned, Subcontinent Asian American-owned small business based in Connecticut, develops advanced photonics, electro-optic, and RF microdevice technologies for defense research as a prime contractor under total small business set-asides, with all ten prime awards concentrated in federal R&D programs and most work performed at its Liberty Township and West Chester Township, Ohio facilities.

Apex's customer base is defense-research-focused and highly concentrated. The Air Force Research Laboratory accounts for 10 of 12 total awards and $7.7 million of $9.2 million combined potential value across the vendor's recent footprint. The Defense Advanced Research Projects Agency and the Department of the Army each hold one award, for $1.2 million and $250 thousand respectively. All three customers are covered 100% of awards by potential value, indicating no customer diversification outside this triad.

Apex's prime capability portfolio centers on next-generation infrared optics, metaoptics, RF filter and acoustic technologies, and solid-state photonics for military systems. Representative work includes a $1.25 million SBIR Phase II definitive contract from the Air Force Research Laboratory (awarded June 9, 2023, completing September 8, 2026) for ultra-fast solid-state spatial light modulator development at West Chester Township; a $1.2 million firm fixed-price SBIR Phase II contract from DARPA (awarded January 12, 2026, completing January 11, 2028) for next-generation ultra-compact RF filter technology with active electronically scanned capability, performed in Liberty Township under a total small business set-aside; and a $1.25 million SBIR Phase II definitive contract from the Air Force Research Laboratory (awarded December 18, 2023, completing September 11, 2026) for bottom-up scalable epitaxial growth of gallium oxide with integrated thermal management for next-generation power electronics. Recent 2026 awards include a $1.8 million definitive contract for infrared metaoptic flat lens arrays and two smaller purchase orders ($200 thousand each) for electrically switchable reflective amplitude modulators and wafer-scale thin film lithium niobate substrate solutions.

Apex operates nearly exclusively under SBIR and STTR programs. Nine of ten prime awards carry SBIR or STTR research designations; all ten are coded to NAICS 541712 (Research and Development in Physical, Engineering, and Life Sciences), with PSC coding split between DoD applied research (5 awards) and basic research (3 awards). Activity peaked in 2023 with five awards, then dropped to one in 2024 before recovering to two in 2025 and three in 2026 year-to-date. Three awards totaling $3.2 million in combined potential value face ultimate completion within the next twenty-four months and will require recompete. Apex sits on an Air Force Research Laboratory indefinite delivery contract (FA865022D5803) with two task orders placed against it. In its subcontractor role, Apex performed photonic crystal analysis and AI/ML-driven neural network training work for Azimuth Corporation on the TECHNICAL OPERATIONS (TOPS) VI program (awarded June 28, 2023). Combined dollars obligated stand at $8.7 million, representing 94% of potential value — indicating active funding and contract maturity across the recent portfolio.
