High index lens including uniaxial or biaxial organic solid material

A method comprising:

• introducing an organic liquid into a mold;
• and
• solidifying the organic liquid into an organic solid to form a Fresnel lens,
• wherein:
• at least one surface of the organic solid comprises a plurality of facets;
• the organic solid comprises uniformly aligned organic molecular crystals, a uniformly aligned refractive index profile, and has optical anisotropy;
• and
• a direction of a maximum refractive index of the organic solid is orthogonal to an optical axis of the Fresnel lens.

A method, comprising:

• forming a patterned surface profile in an organic solid to form a Fresnel lens, wherein:
• the organic solid comprises a uniformly aligned refractive index profile, uniformly aligned organic molecular crystals, and is optically anisotropic;
• and
• a direction of a maximum refractive index of the organic solid is orthogonal to an optical axis of the Fresnel lens.
