Abstract

In this paper we make a review of ring resonators structures for active applications in silicon. Specifically, we analyze and demonstrate microring tunable resonators for thermo-optic tuning and electro-optic modulation. A Thermo-optically tunable Silicon-On-Insulator (SOI) microring demultiplexer with high extinction ratio and low insertion losses is presented and experimentally demonstrated. Concerning Electro-Optic modulation, single ring resonator structures and ring enhanced Mach-Zehnder interferometer (REMZI) structures have been theoretically analyzed. The goal is to take advantage of such structures in terms of extinction ratio, required power consumption and device size to achieve high speed modulation. © Sociedad Española de óptica.
