Abstract
An optical structure includes a substrate including a cavity on a first surface of the substrate, an optical component on the substrate and an adhesive applied to a side of the optical component to fix the optical component to the substrate. The optical component includes a recess on a second surface of the optical component, the second surface is opposed to the first surface of the substrate, and the recess is provided along an edge of the second surface.

A fluid control structure, comprising:
- a first component including a cavity on a first surface of the first component;
- a second component on the first component;
- a hydrophobic area on the first component;
- and
- a gap formed between the first component and the second component, the gap forming a narrow area, and a groove formed on the second component and disposed opposite the hydrophobic area, the groove having a gap height that is larger than a gap height of the narrow area, the groove being adjacent to the narrow area and closer to the cavity than the narrow area, and the groove and the hydrophobic area being configured to suppress infiltration of fluid into the cavity.
