The ring-based resonant router
Proceedings of 2003 5th International Conference on Transparent Optical Networks, 2003., 2004The resonant router (ReR) is an integrated optics crossbar matrix based on ring resonators. Depending on the characteristics of the rings the ReR can operate as cross-connect (X-ReR) or as wavelength router (/spl lambda/-ReR). The analysis of the device, the spectral characteristics and the impact on a high bit rate signal are presented and discussed ...

Observation of stochastic resonance in a ring laser
Annual Meeting Optical Society of America, 1988The phenomenon of stochastic resonance was introduced by Benzi et al.1 to explain the periodicity of the earth’s ice ages. The primary signature of the phenomenon is that the addition of random noise can improve the SNR of a periodically modulated system, relative to that observed with no externally injected noise.

Expressions are derived for the stability parameter, spot size, and wavefront curvature of a Gaussian beam in a ring resonator containing up to four spherical mirrors unequally spaced. Higher-order transverse modes and aperture effects are not considered.

The ring cavity gives flexibility in resonator design, such as ability to incorporate long collimated beam sections with large beam diameters in order to extract power from large volumes of laser media. Particular attention is paid to the non–planar ring resonator because of its novel features and importance in recent applications in the ring laser ...

Plasmonic resonances in hexagonal split-ring resonator
2017 International Conference on Electrical, Computer and Communication Engineering (ECCE), 2017A nanoscale resonator is designed using a hexagonal split ring inside two metal-insulator-metal (MIM) waveguides. The split angle defined by the angular position of the split referring to the axis of the MIM waveguide is varied and thus the transmission properties as well as different plasmonic resonance modes have been investigated by numerical ...

Photoelastic Effect in Silicon Ring Resonator
Extended Abstracts of the 2007 International Conference on Solid State Devices and Materials, 2007The photoelastic effect of Si was measured in a real optical device, a racetrack ring resonator. The sample holder that can induce strain mechanically was fabricated and the strain dependence of resonance wavelength was investigated. The holder can induce a 10-4 order strain and a 0.1 nm order shift of resonance wavelength induced by this strain was ...

Far-Infrared Resonance in Split Ring Resonators
Japanese Journal of Applied Physics, 2004We experimentally investigated the resonance effect of planar metallic split ring resonators (SRRs) in the far-infrared region (FIR) (~10.6 µm). Experimental results indicated that they exhibit resonance around 10.6 µm, implying negative permeability in the FIR region. Furthermore, the ratio of effective dimensions of the SRR cell and the wavelength of

Unstable resonator misalignment in ring and linear toroidal resonators
Applied Optics, 1983Optical axis motion in a ring resonator is investigated as a function of resonator mirror misalignment by constructing an equivalent paraxial model and applying the ray matrix formalism. Analytical expressions are derived for the optical axis motion. The paraxial model of the ring is shown to imply a linear resonator as a specific case, and the ring ...

Dynamics and stability of resonance rings in galaxies
Astronomical & Astrophysical Transactions, 2000We have developed a model for a spheroidal, ring-shaped galaxy. The stars move in a ring with an elliptical cross section at the 1: 1 frequency resonance. The shape of the cross section of the equilibrium ring depends on the oblateness of the galaxy itself, so that the ellipse of the ring cross section is radially extended when the oblateness of the ...
