This WP aims to the design and realization of versatile non-classical light sources based on spontaneous parametric conversion in the infrared. In particular, at telecom wavelengths, it’s possible to exploit all the technology developed for telecommunications for the realization of compact, efficient and robust experimental setups. They are suitable for transportation, and for integration in more complex apparata, to be used in sensing applications and in-field quantum communication.
Moreover, mid-infrared coherent sources will be developed and characterized, aiming to reach stability levels in frequency and emitted power, such to be used for space-level applications.
We designed and built a mid-IR optical parametric oscillator (OPO), pumped by a CW near-IR laser at 1.9 µm, with near-degenerate emission at 3.8 µm.
