Tuning of microring resonators
SPIE Proceedings, 2010Structural imperfections in fabricated microring resonators make post-fabrication tuning of rings useful in order to obtain desired transmission, phase and delay characteristics. Optical trimming of polymer microrings has been demonstrated using photobleaching.

Compact bandwidth-tunable microring resonators
Optics Letters, 2007Using interferometric couplers and thermal tuning, we demonstrate a novel design of compact microring resonators on silicon-on-insulator platform with tunable bandwidth from 0.1 to 0.7 nm. The structures present an extinction ratio higher than 23 dB and a footprint of less than 0.001 mm(2), which are suitable for integrated optical signal processing ...

Proposal of All-Optical Active Microring Logic Gate for Microring Processor
Japanese Journal of Applied Physics, 2012We propose and analyze all-optical active microring logic gates for a microring processor that has various integrated all-optical signal processing functions. The active microring logic gate is composed of an InGaAsP/InP multiple quantum well and is operated on the basis of cross gain modulation (XGM) and cross phase modulation (XPM).

Perforated microring resonators
2016 International Conference Laser Optics (LO), 2016We propose a novel approach to control mode structure of microring resonators using subwavelength hollow core defects. Their influence on mode structure was studied computationally and experimentally.

Coupling of concentric semiconductor microring lasers
Optics Letters, 1998Coupling between whispering-gallery modes of concentric microcavity lasers was analyzed, and a closed-form three-dimensional vectorial solution for the coupled fields was obtained. Experiments performed with concentric gain-guided vertical cavity ring lasers resulted in regimes of resonant coupling in good agreement with the theory.

Advances in Microring Resonators
Integrated Photonics Research, 2003AbstractA new high-index contrast material system is used to realize commercial quality filters based on microring resonators. Widely tunable optical filters and tracking demultiplexers incorporating first to sixth order ring cavities are demonstrated.
