Feasibility of detecting single atoms using photonic bandgap cavities
نویسندگان
چکیده
We propose an atom-cavity chip that combines laser cooling and trapping of neutral atoms with magnetic microtraps and waveguides to deliver a cold atom to the mode of a fiber taper coupled photonic bandgap (PBG) cavity. The feasibility of this device for detecting single atoms is analyzed using both a semi-classical treatment and an unconditional master equation approach. Single-atom detection seems achievable in an initial experiment involving the nondeterministic delivery of weakly trapped atoms into the mode of the PBG cavity. PACS numbers: 42.50.Ct, 32.80.Pj, 03.75.Be, 42.70.Qs

متن کاملElectrically tunable Yb-doped fiber laser based on a liquid crystal photonic bandgap fiber device.
We demonstrate electrical tunability of a fiber laser using a liquid crystal photonic bandgap fiber. Tuning of the laser is achieved by combining the wavelength filtering effect of a tunable liquid crystal photonic bandgap fiber device with an ytterbium-doped photonic crystal fiber. We fabricate an all-spliced laser cavity based on the liquid crystal photonic bandgap fiber mounted on a silicon ...
متن کاملSpectral Selectivity of Photonic Crystal Infrared Photodetectors
In this paper, we present the simulation results on the absorption modification in photonic crystal (PC) structures. For one-dimensional (1D) PC, using transfer matrix method (TMM), we obtained enhanced absorption in both defectfree and defect based PC structures. High absorption (>60%) and small bandwidth (< 0.1 λ0) at defect level were observed with optimal absorption layers of 10-15 for stru...
متن کاملGas Sensor Based on Large Hollow-Core Photonic Bandgap Fiber
One concern in using photonic band-gap fiber (PBGF) as a gas sensor is the response time. In this type of the gas sensors, response time is the time required for gas to diffuse into the hollow-core. So considering a large hollow-core PBGF (HC-PBGF), the response time can be significantly reduced. But in the large HC-PBGF, the fundamental issue is the presence of higher order modes (HOMs). Somet...

Significantly enhanced absorption at the defect mode can be obtained at surfacenormal direction in a dielectric single-defect photonic-crystal-slab, with an absorption enhancement factor greater than 4,000. Complete absorption suppression within the photonic bandgap region can also be observed in defect-free photonic crystal cavities. High spectral selectivity and tunability is feasible with de...
