Patent ID: 8798406

Claim:
Optical logic, the optical logic comprising: an optical input configured to accept an optical signal as input; an optical output configured to provide a modulated optical signal as output; and a plurality of optical gates between the optical input and the optical output, the plurality of optical gates comprising: a first optical gate including a first waveguide adjacent an insulting surface of a substrate and a first absorptive polymer material, wherein the first absorptive polymer material is configured to shift an index of refraction of at least a portion of the first waveguide responsive to a first gate signal; and a second optical gate coupled to the first optical gate, wherein the second optical gate includes a second waveguide adjacent the insulating surface of the substrate and a second absorptive polymer material, wherein the second absorptive polymer material is configured to shift an index of refraction of at least a portion of the second waveguide responsive to a second gate signal.
