Photonic crystal microcavities for chip-based cavity QED

The suitability of recently demonstrated high quality factor (Q), ultra-small mode volume (Veff) graded square lattice photonic crystal microcavities for cavity QED experiments is discussed. In addition to the basic importance of the Q and Veff of such cavities, other issues of both practical and fundamental relevance are considered. Included amongst these are the robustness of the cavity’s per...

Semiconductor Optical Microcavities for Chip-Based Cavity QED

Optical microcavities can be characterized by two key quantities: an effective mode volume Veff, which describes the per photon electric field strength within the cavity, and a quality factor Q, which describes the photon lifetime within the cavity. Cavities with a small Veff and a high Q offer the promise for applications in nonlinear optics, sensing, and cavity quantum electrodynamics (cavity...

Fiber - coupled nanophotonic devices for nonlinear optics and cavity QED

The sub-wavelength optical confinement and low optical loss of nanophotonic devices dramatically enhances the interaction between light and matter within these structures. When nanophotonic devices are combined with an efficient optical coupling channel, nonlinear optical behavior can be observed at low power levels in weakly-nonlinear materials. In a similar vein, when resonant atomic systems ...
