Quantum optics: Boosting photon storage

J.M. Gérard1

  1. J. M. Gérard is in the Nanophysics and Semiconductors Laboratory, CEA/DRFMC/SP2M 17 rue des Martyrs, 38054 Grenoble, France. e-mail: jmgerard@cea.fr

Controlling light confinement inside microcavities is crucial to the development of optoelectronic devices such as miniaturized semiconductor lasers. A welcome step in this direction is the successful design of a toroid-shaped microresonator able to trap photons with unprecedented efficiency.
