Exail’s Er-doped and Er:Yb-doped optical fibers enable the development of low-noise optical amplifiers and high-power optical amplifiers for flying payloads and for optical feeder links in OGSs.
Exail is providing advanced optical technologies for SOLiS—a space laser communications demonstrator launched by the French government—to demonstrate the viability of an optical...

A two-layer Janus TMD converts light through second harmonic generation (SHG), in which the material emits light at twice the frequency of the incoming beam (left). The SHG beam usually forms a six-pointed flower shape, but certain wavelengths of light distort it. Upper right: Symmetrical flower pattern in gray and asymmetrical SHG signal pattern in red.

False color picture of the watermark of a €20 bank note, showing the amplitude of the transmitted terahertz electrical field signal with varying optical parameters of the material; the highest amplitude is shown in red, and the lowest in blue. The image was recorded by Menlo Systems’ TERA K15 THz-TDS system with TERA Image imaging extension unit and ImageLab processing software.
