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

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 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.

Breaking Rayleigh's curse for two unbalanced single-photon emitters: BLESS technique

Rayleigh's criterion states that resolving point sources below the point spread function width is impossible, with error increasing at shorter distances, known as Rayleigh's curse. While detection mode shaping solves this for equal sources, it fails for unbalanced sources with unknown brightness ratios. We propose BLESS, a technique using Beam moduLation and Examination of Shot Statistics, breaking Rayleigh's curse for unbalanced sources. Classical and quantum Cramer-Rao bound calculations show BLESS's strong potential for real imaging experiments.
