In this work, a ring-bus-ring-bus system has been proposed and experimentally demonstrated on a silicon-on-insulator platform to exhibit electromagnetically induced transparency (EIT)-like effect. Significant EIT-like transmission is generated by the coherent interference between a radiant mode and a subradiant mode in the two ring resonators, which are both directly coupled and indirect coupled through...
In experiment, characteristics of silicon microring/racetrack resonators in submicron rib waveguides have been systematically investigated. It is demonstrated that only a transverse-electric mode is guided for a ratio of slab height to rib height h/H=0.5. Thus, these microring/racetrack resonators can only function for quasi-transverse-electric mode, while they get rid of transverse-magnetic polarization...
Characteristics of microring/racetrack resonators, in submicron SOI rib waveguides, have been investigated. The effects of waveguide dimensions, coupler design, roughness, and oxide cladding are considered. Moreover, guided mode, loss and dispersion of such waveguides are analyzed.
