We demonstrate silicon microring carrier-injection-based modulators/switches with waveguide cross-coupling. We tune the modulator extinction ratio by forward-biasing either the microring or cross-coupled waveguide p-i-n diode, while modulating the other. We also demonstrate OR-logic switching functionality by simultaneously applying two different electrical data streams across the microring and cross-coupled waveguide diodes. For both the modulator and the switch, we observe NRZ pattern-dependent optical waveform distortions.
