Phlux Technology is a UK-based semiconductor company, founded in 2020 as a spin-out from the University of Sheffield and headquartered in Sheffield, UK. The company specializes in high-performance infrared sensors, specifically 1550 nm avalanche photodiode (APD) infrared sensors. Its patented Noiseless InGaAs® technology delivers up to 12 times greater sensitivity than traditional InGaAs APDs — a breakthrough that the infrared sensing industry had pursued for over 20 years.
The company’s flagship Aura family of 1550 nm Noiseless InGaAs® APDs offers internal gain exceeding 120×, enabling detection of extremely weak signals while maintaining low noise. These sensors operate at higher temperatures with reduced dependence on cooling and compensation circuitry, making them drop-in replacements for existing APD components. Key applications include long‑distance LiDAR, optical fiber sensing, range finding, and eye-safe infrared detection systems.
