Quantum electrodynamics in modern optics and photonics: tutorial [PDF]

Journal of the Optical Society of America B, 2020
One of the key frameworks for developing the theory of light–matter interactions in modern optics and photonics is quantum electrodynamics (QED). Contrasting with semiclassical theory, which depicts electromagnetic radiation as a classical wave, QED ...

Computational optical imaging with a photonic lantern [PDF]

Nature Communications, 2020
AbstractThe thin and flexible nature of optical fibres often makes them the ideal technology to view biological processes in-vivo, but current microendoscopic approaches are limited in spatial resolution. Here, we demonstrate a route to high resolution microendoscopy using a multicore fibre (MCF) with an adiabatic multimode-to-single-mode “photonic ...

Research and technology organizations as entrepreneurship instruments: the case of the Institut National d’Optique in the Canadian optics and photonics industry

Journal of Innovation and Entrepreneurship, 2023
Research and technology organizations (RTOs) are studied in the innovation policy literature mainly as providers of R&D services and as intermediaries between universities and the private sector. Through the case of the Institut National d’Optique (INO),

Quantum nonlinear optics — photon by photon [PDF]

Nature Photonics, 2014
The realization of strong interactions between individual photons is a long-standing goal of both fundamental and technological significance. Scientists have known for over half a century that light fields can interact inside nonlinear optical media, but the nonlinearity of conventional materials is negligible at the light powers associated with ...

Photonic advantage of optical encoders

Nanophotonics, 2023
Abstract Light’s ability to perform massive linear operations in parallel has recently inspired numerous demonstrations of optics-assisted artificial neural networks (ANN). However, a clear system-level advantage of optics over purely digital ANN has not yet been established. While linear operations can indeed be optically performed very

Nondestructive Detection of an Optical Photon [PDF]

Science, 2013
Nondestructive Photon Detection The click of a photon detector is the usual method for detecting a photon and can be sufficiently sensitive to detect even a single photon. Such a detection process is, however, destructive—the photon is annihilated. Reiserer et al. (
