Whispering gallery modes formed by partial barriers in ultrasmall deformed microdisks.

چکیده
Unexpected formation of regular high-Q whispering gallery modes in a deformed microdisk where the radius is of the order of the vacuum wavelength is explained in terms of partial barriers in phase space. Using a semiclassical approach to determine the action flux of the partial barriers, we successfully predict spectral ranges in which the high-Q modes can exist. Our analysis enables optimization of emission directionality and the Q factor of deformed ultrasmall microcavities.

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...
متن کاملDirectly mapping whispering gallery modes in a microsphere through modal coupling and directional emission
We fabricate slightly deformed fused-silica microspheres in which whispering gallery modes possess remarkably directional escape emission from the microsphere boundary. With efficient free-space excitation and collection, the lateral spatial distribution of whispering gallery modes with different azimuthal mode numbers, m, is directly observed through modal coupling and directional emission. Ex...

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 کاملDirectional single-mode emission from coupled whispering gallery resonators realized by using ZnS microbelts.
Ring microcavities were formed by wrapping ZnS microbelts, which act as the waveguide and gain region of the microcavities on the surface of optical fibers. The ring microcavities with the formation of whispering gallery modes have lasing threshold lower (Q-factor higher) than that of the ZnS microbelts. The excitation of TM modes could also be suppressed by the ring geometries of ZnS microbelt...
