Quantum Optics Seminar by Jeff Kimble

I describe one-dimensional photonic crystals that support a guided mode suitable for atom trapping within a unit cell, as well as a second probe mode with strong atom-photon interactions. A new hybrid trap is analyzed that combines optical and Casimir-Polder forces to form stable traps for neutral atoms in dielectric nanostructures. By suitable design of the band structure, the atomic spontaneous emission rate into the probe mode can exceed the rate into all other modes by more than tenfold. To implement such traps, my colleagues and I are pursuing numerical simulation, device fabrication, and cold-atom experiments with atomic Cesium coupled to 1D photonic crystals fabricated in Silicon Nitride.
