  • MOSCAP RING RESONATOR OPTICAL MODULATOR
    Publication number: 20230017023
    Abstract: A ring resonator optical modulator comprises: an optical region in which optical radiation can propagate in a circular path having an inner radius and an outer radius coincident with an outer perimeter of the ring resonator optical modulator; a MOS capacitor structure having an upper gate device layer and a lower body device layer, and an insulating material being disposed between the upper gate device layer and the lower body device layer; and a cladding region. The optical radiation is confined within the optical region. The insulating material has a first region disposed in the optical region having a first thickness and a second region having a second thickness greater than the first thickness, the second region being disposed radially inwardly from the inner radius of the optical region, such that the optical radiation is radially confined toward the outer side of the inner radius of the optical region.
    Type: Application
