Programmable Liquid-Crystal-on-Silicon Photonic Integrated Circuits with Millions of Degrees of Freedom
This thesis proposes a novel approach to photonics, wherein waveguides are formed entirely within a homogeneous liquid crystal layer using Liquid-Crystal-on-Silicon (LCoS) technology. Utilizing the electro-optical properties of LCs, we demonstrate the theoretical feasibility of inducing refractive …
