Ultrabroadband Electro-Optic Modulator Based on Hybrid Silicon-Polymer Dual Vertical Slot Waveguide
Figure 1
Dual vertical slot waveguide EO modulator. (a) Schematic layout of dual nanoslot waveguides embedded in the CPW, where three-dimensional RF and optical mode profiles in the middle plane along the waveguide propagation direction are shown on the top of slot waveguide. (b) Cross-sectional view of dual slot waveguide, where strong mode confinement and overlap are illustrated in the center slot.
