ABSTRACT:
An optical waveguide bend element is configured to change a direction of travel of light from a first direction to a second direction. The bend element includes a block of material. The block has an input face configured to receive light travelling in the first direction and an output face configured to transmit light travelling in the second direction. The second direction is substantially different from the first direction. The block also has a convex surface defined between the input face and the output face. The convex surface is configured to keep the light within the bend element through total internal reflection.
