Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LP
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. An optical logic gate decision-making circuit, comprising:
a silicon-on-insulator (SOI) wafer platform, the SOI wafer platform comprising non-linear materials and conductive materials combined thereon;
a first optical bus waveguide, wherein the first optical bus waveguide comprises a first input port receiving a first input optical signal and a first output port transmitting a first optical output signal;
a second optical bus waveguide, wherein the second optical bus waveguide comprises a second input port receiving a second input optical signal and a second output port transmitting a second optical output signal; and
an optical logic gate circuit, comprising:
non-linear materials and conductive materials combined such that an optical non-linearity enables an optical logic gate function:
a silicon-based ring cavity filter;
an input bus wave guide comprising a thru port, wherein the enabled optical logic gate function modifies the first input optical signal and the second input optical signal in accordance with a logical AND operation with respect to an output signal at the thru port; and
an output wave guide comprising a drop port, wherein the enabled optical logic gate function modifies the first input optical signal and the second input optical in accordance with a logical excusive or (XOR) operation with respect to the output signal at the drop port.
