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 10):
A method of forming a surface-incident, plasma-enhanced multiple quantum well optical modulator structure comprising:\n forming a multiple quantum well structure comprising at least two layers of two different semiconductor materials; forming at least one metallic layer adjacent to said multiple quantum well; forming at least one dielectric layer on top of said multiple quantum well; forming at least a second dielectric layer underneath said multiple quantum well; said second dielectric layer has a different refractive index from said first dielectric layer; said metallic 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 with a voltage applied on said modulator structure refractive index changes and couples a part of the incident light into at least one mode selected from 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, thereby reducing the internal reflection.
