Self-aligned liquid crystal optical control devices with 2-slit Young’s experiment

Abstract

Toward future optical quantum computing, we have investigated a self-aligned liquid crystal optical control device with 2-slit Young’s experiment. This device can be operated by changing the control of the optical phase of the liquid crystal and we have observed the change in the interference state. To reduce the problem of stray light, the electrode structure was self-aligned, and the alignment of the liquid crystal director was closely changed. As a result, observed voltage change from 0 to 9 V, the “NOT” logic operation was achieved at the sinc function.
