Silicon nitride (Si3N4) waveguide platforms [1,2] are interesting candidates for optical interconnects and sensing applications [3] thanks to high quality passive components, transparency for NIR and visible wavelengths and their compatibility with CMOS process technology. Unfortunately, no native light sources are available for Si3N4 platforms and the integration of active materials, i.e. III-V compounds,...

Here in this work, we study the electro-refractive modulation of CVD grown single layer graphene placed on top of a silicon microring resonator biased using a polymer electrolyte gate. A voltage length product for a phase shift of π, VπL = 2.7 Vmm has been extracted, which is better compared to silicon depletion horizontal and interleaved pn junction type phase modulators and competitive with Silicon-Insulator-Silicon...

Microring based silicon depletion modulators with high extinction ratios (>25dB) are used for high frequency modulation and as resonant photodetectors at 1340nm (O-band). Photocurrent and power enhancement are investigated for mircorings with different Q-factors.
