A High-Q Millimeter-Wave Dielectric-Resonator Bandpass Filter Using Whispering-Gallery Modes
نویسندگان
چکیده
A low-cost millimeter-wave dielectric-resonator filter using a high-order whispering-gallery mode with the coupling of curved microstrip transmission line has been successfully developed for the mode selection in a millimeter-wave optoelectronic oscillator. The achieved 3-dB bandwidth of this filter is 10.5 MHz (loaded quality factor, Q, is about 3,000) or 0.03 percent at 31.5 GHz with a 3-dB insertion loss and more than a 25-dB band-stop attenuation.

Comparative studies on the quality factors of whispering gallery modes and hybrid plasmon photon modes.
We theoretically and experimentally investigate the multipolar hybrid plasmon-photon modes supported by a dielectric-metal core-shell resonator consisting of a dielectric core wrapped by a thin silver shell and the whispering-gallery modes in its pure dielectric counterpart (the dielectric sphere with the same size). We theoretically demonstrate that in a certain wavelength range the achievable...
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 کاملEvaluation of Effective Conductivity of Copper-Clad Dielectric Laminate Substrates in Millimeter-Wave Bands Using Whispering Gallery Mode Resonators
This paper presents a measurement method for determining effective conductivity of copper-clad dielectric laminate substrates in the millimeter-wave region. The conductivity is indirectly evaluated from measured resonant frequencies and unloaded Q values of a number of Whispering Gallery modes excited in a circular disk sample, which consists of a copper-clad dielectric substrate with a large d...
متن کاملContinuous-wave ultraviolet emission through fourth-harmonic generation in a whispering-gallery resonator.
We experimentally demonstrate continuous-wave ultraviolet emission through forth-harmonic generation in a millimeter-scale lithium niobate whispering-gallery resonator pumped with a telecommunication-compatible infrared source. The whispering-gallery resonator provides four spectral lines at ultraviolet, visible, near-infrared and infrared, which are equally spaced in frequency via the cascaded...
متن کاملAtom galleries for whispering atoms: binding atoms in stable orbits around an optical resonator.
The external fields of optical whispering gallery modes may be used to confine atoms in stable orbits around a dielectric microsphere. As an example, a toroidal dipole-force trap (atom gallery) for three-level atoms is investigated, and the possibility of achieving an atomic (matter-wave) resonator is discussed. The extremely small electromagnetic mode volumes and high Q's of the whispering gal...
