Cavity QED with high-Q whispering gallery modes
نویسندگان
چکیده
We report measurements of cavity-QED effects for the radiative coupling of atoms in a dilute vapor to the external evanescent field of a whispering-gallery mode ~WGM! in a fused silica microsphere. The high Q (5310), small mode volume ~10 28 cm ), and unusual symmetry of the microcavity evanescent field enable velocity-selective interactions between fields with photon number of order unity in the WGM and N̄T;1 atoms in the surrounding vapor. @S1050-2947~98!50904-3#

Microtorus: a high-finesse microcavity with whispering-gallery modes.
We demonstrate a 165-mu;m oblate spheroidal microcavity with a free spectral range of 383.7 GHz (3.06 nm), a resonance bandwidth of 23 MHz (quality factor Q approximately 10(7)) at 1550 nm, and finesse F>/=10(4) . The highly oblate spheroidal dielectric microcavity combines a very high Q factor, typical of microspheres, with a vastly reduced number of excited whispering-gallery modes (by 2 orde...
متن کاملChaotic Light: a Theory of Asymmetric Resonant Cavities Jens U. Nöckel and A. Douglas Stone
Spherical and cylindrical dielectric cavities support high Q whispering gallery modes due to total internal reflection of the trapped light. When such a cavity is deformed smoothly the ray dynamics of these modes becomes chaotic in a manner determined by the KAM theory of classical hamiltonian dynamics. The universal properties of the ray dynamics predicted by KAM theory allow a general underst...

Background: Whispering gallery modes (WGM) biosensors are ultrasensitive systems that can measure amount of adsorbed layer onto the micro-cavity surface. They have many applications including protein, peptide growth, DNA and bacteria detection, molecular properties measurements and specific interaction and drug table recognitions due to their high sensitivity, compact size and label free sensin...
متن کاملWhispering gallery modes
Whispering gallery modes are specific resonances (or modes) of a wave field that are confined inside a given resonator (cavity) with smooth edges due to continuous total internal reflection. The most interesting from a practical viewpoint are electromagnetic whispering gallery modes, since they posses many unique properties, such as ultra-high Q-factors, low mode volumes, small sizes of resonat...
متن کاملRoom temperature lasing of InAs/GaAs quantum dots in the whispering gallery modes of a silica microsphere.
We have achieved low threshold lasing of self-assembled InAs/GaAs quantum dots coupled to the evanescent wave of the high-Q whispering gallery modes of a silica microsphere. In spite of high temperature and Q-spoiling of whispering gallery modes due to diffusion and refraction on the high index semiconductor sample, room temperature lasing is obtained with less than 100 quantum dots. This resul...
