Lithium niobate on insulator (LNOI) provides a platform for the fundamental physics
investigations and practical applications of integrated photonics. However, as an …

Microcavity lasers based on erbium-doped lithium niobate on insulator (LNOI), which are
key devices for LNOI integrated photonics, have attracted significant attention recently. In …

We present a second quantization description of frequency-based continuous variables
quantum computation in the subspace of single photons. For this, we define frequency and …

We extensively discuss the Hong–Ou–Mandel experiment by taking an original phase-
space-based perspective. For this, we analyze time and frequency variables as quantum …

We propose new methods to characterize the spectral-temporal distribution of single
photons. The presented protocols take advantage of spectral filtering, frequency …

In this paper, we investigate the influence of the symmetry of the biphoton wave function on
the coincidence measurement of the generalized Mach-Zehnder (MZ) interferometer, where …
