Nanoscale displacement sensing based on nonlinear frequency mixing in quantum cascade lasers

Autor: Mezzapesa, F. P., Columbo, L. L., De Risi, G., Brambilla, M., Dabbicco, M., Spagnolo, V., Scamarcio, G.

We demonstrate a sensor scheme for nanoscale target displacement that relies on a single Quantum Cascade Laser (QCL) subject to optical feedback. The system combines the inherent sensitivity of QCLs to optical re-injection and their ultra-stability i

To monitor the density of photo-generated charge carriers on a semiconductor surface, we demonstrate a detectorless imaging system based on the analysis of the optical feedback in terahertz quantum cascade lasers. Photo-excited free electron carriers

We have measured the real n2 and imaginary β parts of the χ(3) nonlinear susceptibility in polycrystalline ZnS and ZnSe and its anisotropy σ in cubic ZnSe near half-band-gap using femtosecond spectroscopy. We obtain values in good agreement with r
