Optical device and photodetection system

Abstract

An optical device includes a first structure, a second structure, one or more optical waveguide regions, and a seal member. The first structure has a first surface. The second structure has a second surface facing the first surface. The one or more optical waveguide regions are located between the first surface of the first structure and the second surface of the second structure and contain a liquid crystal material. The seal member fixes a spacing between the first structure and the second structure, surrounds the one or more optical waveguide regions, and includes an opening through which the liquid crystal material is injected. A width of the opening in a first direction is greater than a width of the one or more optical waveguide regions in the first direction.
