The broader impact and commercial potential of this Small Business Technology Transfer (STTR) Phase I project lie in advancing light detection technology through the development of highly sensitive detectors capable of sensing a single particle of light at room temperature. Unlike existing technologies that require extreme cooling, these detectors offer greater accessibility and efficiency, with applications spanning satellite communication, secure online communication, national security, and healthcare. In satellite-based optical communication, they can enable faster, more secure, and reliable data transmission, while in cybersecurity, they can strengthen quantum encryption to protect against cyber threats. Their use in defense may enhance surveillance and threat detection, and in healthcare, they may improve medical imaging and diagnostics by increasing sensitivity and accuracy. By supporting data privacy, sustainable and energy-efficient solutions, and global security, this technology addresses critical societal needs. With a rapidly growing $1.5 billion market for space communication and an annual growth rate of 16–30%, these detectors have the potential to drive innovation and create widespread economic and technological advancements. This Small Business Technology Transfer (STTR) Phase I project will address the need for ultrasensitive optical detectors and ranging systems that provide a critical means for information acquisition and perception of the real world.
