Institute presentation

EXALOS AG is a privately-held, technology-driven Swiss company that focuses on the design, development and sales of advanced broadband light sources. The solutions are based on semiconductor optoelectronic technologies, i.e. Superluminescent Light Emitting Diodes (SLEDs) and Swept Source Lasers. SLEDs combine the best features of Light Emitting Diodes (LEDs) and semiconductor laser diodes (LDs).
SLEDs provide a light output with a broadband optical spectrum and low temporal coherence typically seen in LEDs in combination with output powers and high spatial coherence typically seen in LDs. This makes SLEDs the preferred optical broadband source for various applications. Swept sources are external cavity lasers driven by a gain chip medium and a selective wavelength filter consisting of a fast sweeping MEMS in combination with a grating.
All light source technologies are tailored for scientific and industrial applications in the fiber-optic gyroscope, Optical Coherence Tomography (OCT) and Optical Coherence Microscopy (OCM), fiber-optic test equipment and fiber-optic sensor markets. The company is the world-leading supplier of Superluminescent Light-Emitting Diodes and an established partner for custom OEM solutions where SLEDs and Swept Light Sources are combined with driver electronics and optical components.
EXALOS sets its own challenge to regularly present exciting product innovations. Triggered by the strong relations to leading universities, the product range of EXALOS in the field of SLEDs, External Cavity Lasers and Broadband Light Sources is steadily expanding, serving research and industrial applications in many fields. A worldwide customer base in medical, avionics, aerospace, telecom and is relying on EXALOS’ expertise.
To provide customers with the optimum balance of price, time to market, and performance for any given specification, EXALOS has established strategic alliances with technological- and cost leadership partners. This approach gives EXALOS the flexibility to develop solutions tailored for particular customers, markets and applications. EXALOS AG is ISO 9001:2008 certified and located close to Zürich in Switzerland.
To date EXALOS has about 30 employees which are committed to serve the market with best-in-class broadband light sources commercially available.
