Silicon electro-optical modulators

Due to the weak electro-optic effect of silicon, silicon electro-optical modulators suffer from large footprints, hence, high driving capacitance. The speed of the modulator and its power consumption require the minimization of the driving capacitance. Microring resonance-based modulators have shown great potential to reduce the footprint of Si modulators because the light passes multiple times in the waveguide allowing enhanced interaction compared to single-pass devices such as Mach-Zehnder Interferometer (MZI) modulator.
