Abstract: An optical element includes a first layer, a second layer, and a fluid. A first surface of the first layer is configured to change hydrophobicity in response to incoming activation light. Absorbing molecules in the fluid are repelled or attracted to the first surface in response to the hydrophobicity of the first surface.
