Infrared metrology based on quantum interferometry

Goals of project:

Overcoming the limitations of traditional infrared (IR) spectroscopy methods (such as the high background noise of IR detectors, the need for their cryogenic cooling to increase the signal-to-noise ratio, low sensitivity, and high cost) through the technology of quantum interferometry.

Project objective: 

1. Perform calculations of the design (shape and orientation) and regimes of generation of spontaneous parametric down conversion (SPDC) photon pairs in novel nonlinear crystals that include lithium (Li) or silver (Ag) compounds.
2. Assemble and fine-tune an experimental setup for observing SPDC generation over a wide range of wavelengths (from 600 nm to 10 000 nm).
3. Develop variations of the design for a quantum IR microscopy system. 
4. Assemble an experimental setup for quantum IR microscopy.
5. Develop and implement quantum IR microscopy technology in fingerprint mid-IR spectrum range.
