Self-confinement of light whispering gallery waves
5th International Workshop on Laser and Fiber-Optical Networks Modeling, 2003. Proceedings of LFNM 2003., 2004Summary form only given. Among the numerous specific properties of whispering gallery (WG) waves the most important one for the problem considered is that the WG group velocity can be much less than the velocity of light. As a result, the energy density in the WG wave and, consequently, the electric field strength which determines the increase in the ...

Continuous-wave whispering-gallery optical parametric oscillator for high-resolution spectroscopy
Optics Letters, 2015We achieve a continuous operation of a whispering gallery optical parametric oscillator by stabilizing the resonator temperature T on the mK level and simultaneously locking the pump frequency to a cavity resonance using the Pound-Drever-Hall technique.

Whispering gallery modes in rutile resonators at millimeter wave frequencies
13th International Conference on Microwaves, Radar and Wireless Communications. MIKON - 2000. Conference Proceedings (IEEE Cat. No.00EX428), 2002Whispering gallery modes in single crystal rutile resonator were measured at the frequency range 15-30 GHz. Predicted and measured values of resonant frequencies for several WGM were in excellent agreement. Permittivity components parallel and perpendicular to anisotropy axis have been evaluated and their values were /spl epsi//sub /spl perp//=85.8/spl

Acoustic Waves Tunnelling into Whispering Gallery Waves
2003Generation and propagation of acoustic interface waves running along curvilinear weakly contrast boundary of two media are stadied by formal highfrequency asymptotic technique. Two types of interface waves are found. Waves of one type resemble creeping waves, on the convex side of the boundary and have ray representation on the concave side.

Acoustic whispering gallery mode coupling with Lamb waves in liquid
Sensors and Actuators A: Physical, 2013Acoustic whispering gallery modes (WGMs) in a micro-quartz tube immersed in liquid medium, excited by the evanescent wave of a Lamb wave device, are demonstrated. These excited WGMs exhibit characteristics similar to those of optical WGMs, such as narrow periodic transmission dips and a high quality factor.

Integrated terahertz source based on three-wave mixing of whispering-gallery modes
Optics Letters, 2008We propose an integrated terahertz emitter operating at room temperature between 2.4 and 6 THz. Based on difference-frequency generation in a triply resonant Au/AlAs/GaAs/AlAs/Au microcylinder, this nonlinear source is pumped by two near-IR whispering-gallery modes that are excited by InAs quantum dots embedded in the resonator.

Transverse whispering gallery waves in scattering by elastic cylinders
Ultrasonics, 1990Abstract The steady-state problem of a normally incident plane acoustic wave scattered by an infinitely long elastic (aluminium) cylinder embedded in a liquid (water) is considered. The far field form function is analysed as a function of x = ka . The modal resonance components are joined into families. It is shown that in the region 0 ⩽ x ⩽ 50,

Interaction of whispering-gallery electromagnetic waves with acoustic waves in tapered quartz rods
Quantum Electronics, 2001The propagation of whispering-gallery waves in a dynamic cavity formed by a tapered quartz rod and the plane interface between two regions of the rod with different refractive indices moving along the axis of the rod is analysed. It is shown that the limiting frequency shift of light in such a cavity is determined by its Q factor and the attainable ...
