Abstract

Optical deflectors are key component of free-space optical interconnection equipment.¹ We propose a new type of optical deflector with a prism array structure. It takes about 1 second to change the re­fractive index of ordinary liquid crystal (LC) prisms.² To improve on this operating speed, we use a polymer dispersed liquid crystal (PDLC), which operates at higher speed due to interaction between the polymer matrix and LC molecules.
