Infra-red Micro-Optics
The mid-infrared region of the optical spectrum is important for spectroscopic and laser applications, since many toxic and greenhouse gases have absorption lines in this region. A tunable infrared source is able to probe these absorption peaks and hence can serve as a remote detector for these gases. Micro-structuring infrared components is an innovative way to develop optical elements and devices for this wavelength range.
In particular, a Chromium-doped Zinc Selenide laser with emission wavelengths of 2 to 3 micrometer is under development. Wavelength tuning will be accomplished by a resonant grating in a Germanium layer which is deposited on a copper substrate. This grating serves as end mirror of the Zinc Selenide laser resonator.
