Optical microcavities confine light to small volumes by resonant recirculation. Devices based
on optical microcavities are already indispensable for a wide range of applications and …

The coherent exchange of energy between materials and optical fields leads to strong light–
matter interactions and so-called polaritonic states with intriguing properties, halfway …

A new class of composite materials has emerged which provides a means to control and
manipulate light. These materials, known as photonic crystals, are periodic arrays of …

Photonic cavities that strongly confine light are finding applications in many areas of physics
and engineering, including coherent electron–photon interactions, ultra-small filters,, low …

This Review covers photonic crystals (PhCs) and their use for sensing mainly chemical and
biochemical parameters, with a particular focus on the materials applied. Specific sections …

Distributed quantum networks will allow users to perform tasks and to interact in ways which
are not possible with present-day technology. Their implementation is a key challenge for …

The quest for all-optical signal processing is generally deemed to be impractical because
optical nonlinearities are usually weak. The emerging field of nonlinear photonic crystals …

Modern cavity quantum electrodynamics (cavity QED) illuminates the most fundamental
aspects of coherence and decoherence in quantum mechanics. Experiments on atoms in …

Hybrid quantum devices, in which dissimilar quantum systems are combined in order to
attain qualities not available with either system alone, may enable far-reaching control in …

Possible future changes in Arctic sea ice cover and thickness, and consequent changes in
the ice-albedo feedback, represent one of the largest uncertainties in the prediction of future …
