Little big photon

Vladan Vuletić

Published May 1, 2015• 0 citations
Publisher

Abstract

A photon, the constituent particle of light, carries only a tiny amount of energy. Furthermore photons do not interact with one another in vacuum, and generally only very weakly in optical media. Nonetheless, it has recently become possible for a single photon to switch on or off hundreds of other photons, or to generate entanglement between thousands of atoms.

Single photons on demand

Philippe Grangier, Izo I. Abram

QUANTUM mechanics has gained a reputation for making counterintuitive predictions. But we rarely get the chance to witness these effects directly because, being humans, we are simply too big. Take light, for example. The light sources that are familiar to us, such as those used in lighting and imaging or in CD and DVD players, are so huge that they emit billions and billions of photons. But what if there was a light source that emitted just one photon at a time?

Efficient All-Optical Switching Using Slow Light within a Hollow Fiber

Vlatko Balić, Alexander S. Zibrov, Sebastian Hofferberth +5 more

We demonstrate a fiber-optical switch that is activated at tiny energies corresponding to a few hundred optical photons per pulse. This is achieved by simultaneously confining both photons and a small laser-cooled ensemble of atoms inside the microscopic hollow core of a single-mode photonic-crystal fiber and using quantum optical techniques for generating slow light propagation and large nonlinear interaction between light beams.

Light and Optics

Andrew Rex

You’ve also seen that the electromagnetic wave alone is insucient to describe how light behaves (Chapter 4). Rather, light consists of small quanta of energy called photons. In carefully designed experiments, individual photons can be detected and counted. A complete view of light includes both waves and particle-like photons, and we are left to contemplate the resulting waveparticle duality.

Routing one photon with a few others

I. S. Osborne

Quantum Optics Single particles of light, photons, are ideal carriers of quantum information because they can travel far and fast and don't interact much with each other. However, this behavior has hampered attempts to control the propagation of single photons using all-optical setups. Shomroni et

Nonlinear optics and quantum entanglement of ultra-slow photons

Mikhail D. Lukin, Ataç İmamoğlu

Summary form only given. Exciting observations of ultra-slow group velocities and very large nonlinearities in coherently driven atomic media open up interesting prospectives for nonlinear optical processes at low light levels. Recent experiments, for instance, demonstrated that very efficient nonlinear phenomena can be induced by laser fields of tiny energies. These developments stimulate the studies of ultimate efficiency limits for nonlinear optics based on electromagnetically induced transparency (EIT) as well as its possible applications for generation and manipulation of quantum entangled states of the light fields and matter. We describe a particular method that allows for two slow light fields of energies corresponding to that of a single photon to interact coherently.
