Photonic Crystal Ring Resonators and Ring Resonator Circuits

2010
We present the characteristics and applications of photonic crystal ring resonators (PCRR). Photonic crystal confinement can achieve very high cavity quality factor ring resonators. Diffraction-limited ultra-compact PCRRs are feasible due to the absence of size-dependent losses.

Resonant Frequency of Slotted Ring Resonator

30th European Microwave Conference, 2000, 2000
The slotted ring resonator has some promising features for the realisation of compact microwave filters. For the first time, using the finite difference technique and conformal mapping method, the effects of geometrical parameters (i.e.: the resonator length, inner radius, gap width and wall thickness) on the resonant frequency of this resonator, are ...

The ring-based optical Resonant Router

2006 IEEE International Conference on Communications, 2006
The 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 (?-ReR). The analysis of the device, the spectral characteristics and the impact on a high bit rate signal are presented and discussed both on ...

Observation of stochastic resonance in a ring laser

Annual Meeting Optical Society of America, 1988
The 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.

Plasmonic ring resonator

Journal of the Optical Society of America B, 2008
A ring resonator composed of a plasmonic waveguide is presented. For the plasmonic waveguide, an array of silver nanorods is assumed. To determine the modes of this ring resonator, the generalized multipole technique (GMT) is used. Using this analysis, we obtain various modes of the proposed ring resonator.

Fiber Ring Resonator

SPIE Proceedings, 1984
All-fiber ring resonators using ultra low loss directional couplers have been fabricated with finesse as high as 500. Resonator finesse is no longer limited by coupler loss and can be increased by lowering fiber loop loss. New polarization effects in the resonator have been observed indicating polarization dependent coupling in the directional coupler.

Ring resonator thermometry

2016 IEEE Photonics Conference (IPC), 2016
We report on our study of a temperature response of ring resonator based sensors and their interchangeability over a wide temperature range. Our results suggest that with a proper fabrication process control the interchangeability in photonic thermometers can be on a 0.2 °C tolerance band.

An unstable ring resonator

IEEE Journal of Quantum Electronics, 1973
An unstable ring resonator has been studied, both theoretically and experimentally; quasi-traveling-wave operation is obtained with a high ratio of the powers of the two opposite rotating waves and with diffraction-limited output beams.
