Abstract
An optical waveguide body includes a first layer of optically transmissive material and a second layer of optically transmissive material in contact with the first layer. At least one of the first and second layers is tapered and the first layer has a first index of refraction and the second layer has a second index of refraction less than the first index of refraction and the first and second indices of refraction are both greater than about 1.0.
Claims20
An optical waveguide body, comprising:
- a first layer of optically transmissive material comprising a thickness defined by a first side and second side;
- a second layer of optically transmissive material defined by a third side and a fourth side opposite the third side, wherein a first ridge of the second side extends into the second layer and a second ridge of the third side extends into the first layer;
- wherein the second layer comprises a plurality of further ridges and grooves disposed on the fourth side thereof;
- wherein the first side and fourth side are tapered toward one another;
- wherein the first layer has a first index of refraction and the second layer has a second index of refraction less than the first index of refraction and wherein the first and second indices of refraction are both greater than about 1.0.
