This work presents a novel ring resonator design. The demonstrated hybrid-waveguide ring resonator takes advantage of both, a highly effcient slot-waveguide based phase shifter and a low loss strip-waveguide in a single ring. The device is realized on 200 mm silicon-on-insulator wafers and covered by an electro-optic polymer in a post-processing step. The fabricated device has a small footprint and low optical losses, while at the same time a remarkable...
