They offer considerable wavelength tunability, high output power, high-speed modulation capabilities and may be fabricated in several different materials systems.
Gmachl has demonstrated mid-infrared light sources for a wide range of applications, including trace gas sensing in the environmental, industrial, and medical fields, and free-space optics in wireless communications.
