Here, we propose a mid-infrared enhanced plasmonic modulator that integrates double-layer graphene in a reflective structure. It is demonstrated that double-layer graphene can support plasmonic resonances with higher oscillator intensity than single-layer in this modulator. The proposed modulator exhibits...
A method for fabricating an optical modulator includes forming n-type layer, a first oxide portion on a portion of the n-type layer, and a second oxide portion on a second portion of the n-type layer, patterning a first masking layer over the first oxide portion, portions of a planar ...
An optical modulator device includes a body portion operative to propagate an optical mode along a longitudinal axis of the body portion, the body portion comprising a first layer disposed on a second layer, wherein the first layer includes a first p-type doped region adjacent to a first n-...
