Interaction of whispering-gallery electromagnetic waves with acoustic waves in tapered quartz rods

Quantum Electronics, 2001
The 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 ...

High-Q whispering gallery travelling wave resonators for oscillator frequency stabilisation

Proceedings of the 1999 Joint Meeting of the European Frequency and Time Forum and the IEEE International Frequency Control Symposium (Cat. No.99CH36313), 2000
Usually a frequency-stabilized standing wave resonator-oscillator incorporating a resonator as a frequency discriminator requires a circulator to separate the injected and reflected wave, A ferrite circulator is a noisy device and can limit the phase noise or frequency stability. Moreover, we show that the noise in a circulator varies, and detailed low

Continuous-wave whispering-gallery optical parametric oscillator for high-resolution spectroscopy

Optics Letters, 2015
We 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.

Integrated terahertz source based on three-wave mixing of whispering-gallery modes

Optics Letters, 2008
We 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.

Generation of Continuous-Wave UV, Visible, and Near-IR Waves in a Whispering-Gallery Resonator

Frontiers in Optics 2011/Laser Science XXVII, 2011
We experimentally demonstrate generation of continuous-wave UV, visible, and near-IR waves in a periodically-poled lithium niobate whispering-gallery resonator pumped with a telecommunication-compatible IR source, at a record-low pump power of 200mW.

Terahertz Broadband Whispering-Gallery Mode Gyrotron Backward-Wave Oscillator

IEEE Transactions on Electron Devices, 2019
Conventional gyrotron backward-wave oscillators (gyro-BWOs) operate in a low-order mode, e.g., TE $_{0,1}$ mode. As the operating frequency extends to the terahertz (THz) band, the transverse size of low-order mode cavity shrinks, and the power capability is reduced, consequently.

Polarization and losses of whispering-gallery waves along twisted trajectories

Journal of the Optical Society of America, 1979
A geometrical optics treatment shows that whispering-gallery waves following twisted trajectories can be in eigenstates of polarization if σ = (radius of curvature × torsion) is a constant. The Jones vectors of these eigenpolarizations are calculated, along with their propagation constants and power attenuation constants.

Radiation field of whispering gallery waves over a concave-convex boundary

Journal of Soviet Mathematics, 1982
In this work the wave field arising over a concave-convex reflecting boundary is studied in the Kirchhoff approximation. The field arises as a result of the incidence of whispering gallery waves on an inflection point of the boundary from the concave side.
