متن کاملCoupling-induced resonance frequency shifts in coupled dielectric multi-cavity filters.
Coupling-induced resonance frequency shifts (CIFS) are theoretically described, and are found to be an important fundamental source of resonance frequency mismatch between coupled optical cavities that would be degenerate in isolation. Their deleterious effect on high-order resonant filter responses and complete correction by pre-distortion are described. Analysis of the physical effects contri...
متن کاملResonance widths in open microwave cavities studied by harmonic inversion.
From the measurement of a reflection spectrum of an open microwave cavity, the poles of the scattering matrix in the complex plane have been determined. The resonances have been extracted by means of the harmonic inversion method. By this, it became possible to resolve the resonances in a regime where the linewidths exceed the mean level spacing up to a factor of 10, a value inaccessible in exp...
متن کاملTerahertz Dipole Nanoantenna Arrays: Resonance Characteristics
Resonant dipole nanoantennas promise to considerably improve the capabilities of terahertz spectroscopy, offering the possibility of increasing its sensitivity through local field enhancement, while in principle allowing unprecedented spatial resolutions, well below the diffraction limit. Here, we investigate the resonance properties of ordered arrays of terahertz dipole nanoantennas, both expe...
متن کاملThree-dimensional field structure in open unstable cavities Part II: Active cavity results.
The three-dimensional field distribution of the diffractive cavity mode structure in an active, open, unstable laser resonator is presented as a function of the equivalent Fresnel number of the cavity. The active cavity mode structures are compared to that of the corresponding passive cavity so that the effects of a spatially extended, homogeneously broadened, saturable gain medium on the cavit...
