Latest Patents

Nissim Ben-Yosef holds a patent for a "Silicon light waveguide with MOS capacitors positioned on the waveguide." This invention provides a silicon waveguide with a silicon oxide cladding on a silicon substrate. At predetermined positions along the length of the waveguide, metal oxide semiconductor (MOS) structures are created. A conductive layer is deposited and patterned above the upper cladding, allowing for electrical contacts to be made. The application of a potential difference between the layers changes the free carrier concentration, which in turn alters the index of refraction. This change affects the optical mode propagating in the waveguide, enabling controlled propagation through the manipulation of the electric field.
