The overall goal of photonics research is to understand and control light in new and richer
ways to facilitate new and richer applications. Many major developments to this end have …

We propose a device consisting of m Mach-Zehnder interferometers and realizing sorting of
the first 2 m temporal Hermite-Gauss modes of light passing through it by adjusting the …

A time lens allows one to stretch or compress optical waveforms in time, similar to the
conventional lens in space. However, a single-time-lens imaging system always imparts a …

We propose an application of quantum temporal imaging to restoring the indistinguishability
of the signal and the idler photons produced in type-II spontaneous parametric down …

We discuss the spatial and spectral properties of electromagnetic fields in a squeezed
vacuum state and consider photon correlations in such fields. We concentrate on a bright …

High-dimensional entanglement is a critical foundation for the growing demand for
information capacity to implement the high-capacity quantum task. Here, we report …

Starting with Maxwell's equations and defining normal variables in the Fourier space, we
write the equations of temporal evolution of the electromagnetic field with sources in the …

Frequency-degenerate pulsed type-I parametric downconversion is a widely used source of
squeezed light for numerous quantum optical applications. However, this source is typically …

We present a single-pass source of broadband multimode squeezed light with potential
application in quantum information and quantum metrology. The source is based on a type I …

Entangled two-photon absorption (ETPA) could form the basis of nonlinear quantum
spectroscopy at very low photon fluxes, since, at sufficiently low photon fluxes, ETPA scales …
