Optical waveguides

摘要

An optical waveguide includes a coupling optic and a waveguide body. According to one embodiment, the body includes a first curved surface that extends between an input surface and an end surface and a second surface opposite the first surface. The input surface has a first thickness disposed between the first and second surfaces and the end surface has a second thickness disposed between the first and second surfaces less than the first thickness.

主权项

1. An optical waveguide body, comprising:
a first surface that extends between an input surface and an end surface; a second surface opposite the first surface wherein a body thickness is disposed between the first and second surfaces; wherein the body thickness at the input surface is greater than the body thickness at the end surface and the body thickness between the input surface and end surface decreases over a length of the body; and at least one stepped feature defined by first and second oblique angles on one of the first and second surface; wherein the first surface is curved along an entire first extent between the input surface and the end surface, and wherein the first surface is curved along an entire second extent between side surfaces wherein the first extent is orthogonal to the second extent.
