Resonance splitting in gyrotropic ring resonators
Optics Letters, 2010We present the theoretical concept of an optical isolator based on resonance splitting in a silicon ring resonator covered with a magneto-optical polymer cladding. For this task, a perturbation method is derived for the modes in the cylindrical coordinate system. A polymer magneto-optical cladding causing a 0.01 amplitude of the off-diagonal element of

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.

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.

Photonic Crystal Ring Resonators and Ring Resonator Circuits
2010We 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.

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.

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.

Resonant Frequency of Slotted Ring Resonator
30th European Microwave Conference, 2000, 2000The 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 ...

This work presents the investigation of the interplay between two different types of losses in plasmonic ring resonators: i) the losses associated with the finite curvature radius and ii) the ohmic losses associated with the penetration of the electromagnetic fields inside the metal.

Polarization conversion in ring resonators
The 17th Annual Meeting of the IEEELasers and Electro-Optics Society, 2004. LEOS 2004., 2004The effect of the polarization rotation in bent waveguide on the frequency response of optical ring resonators is theoretically and experimentally investigated. A simple model that fairly well agrees with measured spectral responses is proposed.
