Terahertz Broadband Whispering-Gallery Mode Gyrotron Backward-Wave Oscillator
IEEE Transactions on Electron Devices, 2019Conventional 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.

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.

The asymptotics is constructed as t→∞ for the wave field generated by a whispering-gallery wave incident on an inflection point of the boundary. The asymptotics has ray character and is connected with the family of rays tangent to the convex part of the boundary beyond the point of inflection.

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.

Generation of Continuous-Wave UV, Visible, and Near-IR Waves in a Whispering-Gallery Resonator
Frontiers in Optics 2011/Laser Science XXVII, 2011We 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.

Ultrahigh-Quality microcavity with whispering-gallery-mode (WGM) is a new kind of resonator with high quality. The evanescent wave of WGM plays an important role in surface enhanced Raman scattering (SERS). In this paper we study the relationship between coupling coefficient and evanescent wave of the WGM and the coupling character difference between ...

the whispering gallery waves in a disk dielectric resonator located on a dielectric substrate
Radioelectronics and Communications Systems, 2006The paper is devoted to investigation of peculiarities of natural azimuthal electromagnetic oscillations in a dielectric resonator located on a substrate, whose permittivity is lower than that of the material of the main resonator. The impact of the dielectric substrate thickness on the spectrum of natural frequencies of the resonant structure is ...
