US 2015/0316830 A1 · OPTICAL LOGIC CIRCUIT OPERATING BY CONTROLLING REFLECTION OF LIGHT AND COMPUTING DEVICE USING SAID OPTICAL LOGIC CIRCUIT

Abstract

The disclosed optical logic circuit operating by controlling the reflection of light comprises: a first waveguide, at least a portion of which is formed into the shape of a straight line; a second waveguide branched at a predetermined angle from the first waveguide; and a first reflector having a refractive index that varies based on a first input signal, the first reflector selecting either the first waveguide or the second waveguide as a pathway of light. The value of the signal of a first output terminal provided through the first waveguide and the value of the signal of a second output terminal provided through the second waveguide can be adjusted using the first input signal.

Dependent claims

An optical logic circuit operating with light reflection control, comprising:

a first waveguide configured to have at least a portion formed into a shape of straight line;
a second waveguide configured to branch with an angle from the first waveguide;
and
a first reflector configured to change a refractive index by a first input signal and control a pathway of light to be selected into one of the first waveguide and the second waveguide,
wherein the first input signal is used to control a signal value of a first output terminal through the first waveguide and a signal value of a second output terminal through the second waveguide.
