Time-domain Hong-Ou-Mandel interference of quasi-thermal fields and its application in linear optical circuit characterization

Opt Lett. 2022 Sep 15;47(18):4708-4711. doi: 10.1364/OL.464120.

Abstract

We study temporal correlations of interfering quasi-thermal fields, obtained by scattering laser radiation on a rotating ground glass disk. We show that the Doppler effect causes oscillations in the temporal cross correlation function. Furthermore, we propose how to use Hong-Ou-Mandel interference of quasi-thermal fields in the time domain to characterize linear optical circuits.
