Problem
Accurate detection of trace gases, liquids, and solid components often requires bulky, expensive laser equipment and specialized expertise, limiting widespread adoption in environmental monitoring, healthcare, safety, and automotive applications.
Solution
Sensalight Technologies manufactures compact, high‑performance semiconductor lasers and mid‑IR light‑emitting diodes tailored for real‑time sensing across gas, liquid, and solid media. Their continuous‑wave distributed feedback (DFB) lasers provide single‑mode, longitudinal output optimized for specific gases, while widely tunable monolithic lasers cover broad wavelength ranges for diverse analytes. Mid‑IR LEDs based on interband cascade heterostructures extend detection capabilities into the 2.8–6.5 µm region. All devices are produced in a vertically integrated, ISO‑9001 certified cleanroom, ensuring consistent quality and reliability for high‑volume applications. In addition, Sensalight offers nanofabrication services—including electron‑beam lithography, surface coating, and dry etching—to customize photonic components for customer‑specific sensor systems.
