Sivananthan Laboratories, Inc.

Sivananthan Laboratories, Inc., a minority-owned, Subcontinent Asian American-owned small business based in Bolingbrook, Illinois, conducts advanced infrared imaging, quantum sensing, and materials research for the Department of Defense and related agencies under Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) contracts and federal grants. The company operates as a prime contractor on 98% of its federal awards, competing exclusively under total small business set-asides across SBIR Phase I and Phase II programs.

Sivananthan's capability portfolio centers on metasurface-coupled detection systems, focal plane arrays, superlattice imaging technologies, and radiation-hardened photodetector modeling. Representative recent work includes a $1.8 million SBIR Phase II contract from the Air Force Research Laboratory (awarded August 2025, running through August 2027) for metasurface-coupled mercury cadmium telluride alloys for nonreciprocal optical limiting; a $1.5 million SBIR Phase II contract from the Missile Defense Agency (awarded March 2024, running through March 2027) for multiscale modeling of radiation events in infrared photodetectors; and a $750 thousand SBIR Phase II contract from the Air Force Research Laboratory (awarded May 2024, running through August 2026) for design and development of a specialized two-color focal plane array and imaging system in a low-size, weight, power, and cost configuration. Federal grant work includes a $400 thousand project grant from the Department of Energy Office of Science (awarded June 2022, completed June 2023, CFDA 81.049) for metasurface-coupled avalanche photodiode research and a Department of Energy Office of Science project grant for AI-guided, multi-modal, multi-scale anomaly detection in scanning transmission electron microscopy and electron energy loss spectroscopy (awarded February 2022, running through April 2025).

Customer concentration is heavily skewed to Defense Department research establishments. The top five funding agencies account for 85% of awards by count and 97% of combined potential value: the Air Force Research Laboratory leads with 13 awards valued at $6.6 million combined, followed by the Missile Defense Agency (9 awards, $5.7 million), the Army Materiel Command Research Development and Engineering Command (10 awards, $5.2 million), DARPA (5 awards, $3 million), and NASA (4 awards, $1.1 million). The Air Force and Missile Defense Agency together anchor the portfolio with over half of all dollars obligated.

Activity trajectory shows modest volume with intermittent clustering in SBIR submission cycles — four awards in 2022, two in 2023, five in 2024, then one each in 2025 and 2026 — and a combined potential value of $22.3 million across 48 prime and sub awards since 2011. Four awards with combined potential value of $4.2 million face ultimate completion within the next twenty-four months, representing near-term recompete exposure. The company's sub-award footprint is minimal: a single sub-award to Virginia Commonwealth University in April 2024 for Convergence Lab Initiative recruitment and support work, indicating Sivananthan operates primarily as a direct-to-government research performer rather than a subcontractor integrator.
