Abstract:
An optical interconnect system has first and second waveguides each with wedge-shaped cross-section at a first end, disposed over an optical modulator. The optical modulator is a surface-plasmon multi quantum well (SP-MQW) modulator, the first waveguide an input waveguide and the second waveguide configured an output waveguide. In embodiments the SP-MQW modulator has multiple semiconductor layers disposed atop a lower metal layer between 10 and 300 nanometers thick and configured such that incident light is reflected at the lower metal layer unless a voltage is applied to the semiconductor layers, when incident light is coupled into a surface plasmon mode in the lower metal layer.

Claim (Index 9):
A surface-incident, plasmon-enhanced, multiple quantum well optical modulator comprising:\n a multiple quantum well structure comprising at least two layers of two different semiconductor materials; at least one metallic layer adjacent to said multiple quantum well structure; at least one dielectric layer on top of said multiple quantum well structure; at least a second dielectric layer underneath said multiple quantum well; said second dielectric layer having a different refractive index from said first dielectric layer; said metal layer being also adjacent to one of said dielectric layers; where light is incident through one of said dielectric layers with a higher refractive index on one surface of said multiple quantum well; the incidence angle being large enough to allow total internal reflection at a second surface of said multiple quantum well when no voltage is applied on said modulator structure; while applying a voltage on said modulator structure changes the refractive index and absorption coefficient of said multiple quantum wells and couples the incident light into at least one mode selected from the group consisting of a surface plasmon mode propagating on the surface of said metal layer and coupled modes between said surface plasmon mode and metal/MQW/metal guided modes.
