Abstract

An optical device includes a reflector layer having a first surface, a second surface opposite the first surface; a third surface, and a fourth surface opposite the third surface; and a first selective light modulator layer external to the first surface of the reflector layer; in which at least one of the third surface and the fourth surface includes an azimuthal modulator layer. A method of making an optical device is also disclosed.

First claim

What is claimed is:

1. An optical device, comprising:
a reflector layer having a first surface, a second surface opposite the first surface; a third surface, and a fourth surface opposite the third surface;
a first selective light modulator layer external to the first surface of the reflector layer;
a second selective light modulator layer external to the second surface of the reflector layer;
a first azimuthal modulator layer present on the third surface of the reflector layer; and
a second azimuthal modulator layer present on the fourth surface of the reflector layer;
wherein each of the first and second azimuthal modulator lavers independently include at least one colorant chosen from pigments and dyes;
wherein the second selective light modulator layer is external to a second end of each of the first and second azimuthal modulator layers.

2. The optical device of claim 1 , wherein the first selective light modulator layer is external to a first end of each of the first and second azimuthal modulator avers.

3. An optical device, comprising:
a reflector layer having a first surface, a second surface opposite the first surface; a third surface, and a fourth surface opposite the third surface;
a first selective light modulator layer external to the first surface of the reflector layer;
a first azimuthal modulator layer present on the third surface of the reflector laver; and
a second azimuthal modulator layer present on the fourth surface of the reflector layer;
wherein each of the first and second azimuthal modulator lavers independently include at least one colorant chosen from pigments and dyes;
wherein the first selective light modulator layer incudes a third surface opposite a fourth surface, and the first azimuthal layer is external to the third surface of the first selective light modulator layer.

4. The optical device of claim 3 , wherein the second azimuthal layer is external to the fourth surface of the first selective light modulator layer.

5. An optical device, comprising:
a reflector layer having a first surface, a second surface opposite the first surface; a third surface, and a fourth surface opposite the third surface;
a first selective light modulator layer external to the first surface of the reflector layer;
a second selective light modulator layer external to the second surface of the reflector laver;
a first azimuthal modulator layer present on the third surface of the reflector layer; and
a second azimuthal modulator layer present on the fourth surface of the reflector layer;
wherein each of the first and second azimuthal modulator layers independently include at least one colorant chosen from pigments and dyes;
wherein the second selective light modulator layer incudes a third surface opposite a fourth surface, and the first azimuthal layer is external to the third surface of the second selective light modulator layer.

6. The optical device of claim 5 , wherein the second azimuthal layer is external to the fourth surface of the second selective light modulator layer.

7. The optical device of claim 1 , wherein the first selective light modulator layer provides a first color attribute to the optical device.

8. The optical device of claim 1 , wherein the first azimuthal modulator layer provides a second color attribute to the optical device.

9. The optical device of claim 8 , wherein the second color attribute is different from a first color attribute.

10. The optical device of claim 7 , wherein the first color attribute is present at a first viewing angle.

11. The optical device of claim 9 , wherein the second color attribute is present at a second viewing angle.

12. The optical device of claim 11 , wherein the second viewing angle is different from a first viewing angle.

13. The optical device of claim 1 , wherein the reflector layer includes a colored material.

14. The optical device of claim 1 , wherein the reflector layer is a colored metal chosen from copper, gold and bronze.

15. An optical device, comprising:
a reflector layer having a first surface, a second surface opposite the first surface; a third surface, and a fourth surface opposite the third surface;
a first selective light modulator layer external to the first surface of the reflector layer;
a first azimuthal modulator layer present on the third surface of the reflector layer; and
a second azimuthal modulator layer present on the fourth surface of the reflector layer;
wherein each of the first and second azimuthal modulator lavers can independently include at least one of pigments and dyes;
wherein the reflector layer is a colored polyacetylene.
