About LongWave Photonics
LongWave Photonics is a California-based company founded in 2010 by Alan Lee and Qing Hu, specializing in terahertz quantum cascade laser (QCL) systems for imaging, spectroscopy, and heterodyne receivers. Based in Mountain View, California’s Silicon Valley, LongWave Photonics offers compact, turnkey terahertz QCL systems with milliwatt average power levels available across frequencies from 1.9 to 5 THz. The company’s systems operate cryogen-free, require no optical alignment, and provide convenient terahertz sources for research and industrial applications. LongWave Photonics has received funding from institutional investor Innobridge Capital and the National Science Foundation through SBIR grants supporting NASA-related quantum photonics projects. The company’s terahertz quantum cascade lasers serve quantum sensing, spectroscopy, and imaging applications requiring compact, reliable terahertz radiation sources. LongWave Photonics addresses the terahertz gap in the electromagnetic spectrum, providing quantum photonics solutions for security screening, materials characterization, astronomical detection, and fundamental physics research requiring terahertz frequency sources.
2025 Developments: The company continues its quantum technology initiatives throughout 2025. Focus remains on advancing core technologies and expanding market presence. Ongoing development activities position the company for future growth in the quantum industry.
