Latest Patents

One of his latest patents is the Electroabsorption Optical Modulator. This device operates based on the electroabsorption of a surface plasmon polariton mode, improved by various structural changes and the selection of different materials. For instance, portions of the waveguide can be made conductive through doping. Additionally, layers that constitute the modulator structure may be positioned along the sides of waveguides, rather than solely on top. High permittivity gate dielectric materials are utilized, and alternative materials to ITO can serve as transparent conductors. This advanced plasmonic electroabsorption modulator can be fabricated using standard semiconductor processing techniques and integrated with photonic integrated circuits, including silicon photonics and compound semiconductor-based platforms. This innovation allows for high-speed, low-voltage operation across a wide spectrum of wavelengths.

Another notable patent involves methods of epsilon-near-zero optical modulation. This method is applied in a non-resonant epsilon-near-zero (ENZ) plasmonic electro-optical modulator. An optical carrier is injected into a waveguide that is optically coupled to a layer of transparent conductive material with an ENZ wavelength. This layer forms part of a capacitive structure that includes a gate dielectric layer. By applying a time-varying bias voltage across the gate dielectric layer, the ENZ wavelength shifts toward the carrier wavelength, thereby creating a phase modulation pattern on the carrier wave.
