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

Claim 3:
4. The optical logic gate decision-making circuit of claim 1, further comprising a 2X1 adder receiving the first input optical signal and the second input optical signal, and wherein modifying the first input optical signal and the second input optical signal in accordance with a logical AND operation with respect to the output signal at the optical thru port, comprises:
receiving the first input optical signal at a field intensity that is equal to the resonant wavelength of the silicon-based ring cavity filter and the second input optical signal at a field intensity that is also equal resonant wavelength of the silicon-based ring cavity filter; and
the silicon-based ring cavity filter receiving the sum of the field intensity of the first optical wavelength and the field intensity of the second optical wavelength from the 2X1 adder such that the optical non-linearity modifies the resonant wavelength of the silicon-based ring cavity filter; and
modifying the first input optical signal to a have a field intensity that is equal to a logical “1” at the thru port.
