Abstract
A monolithically integrated optical assembly comprising a waveguide configured to receive light and a coupling element configured to couple light into the waveguide. The monolithically integrated optical assembly comprises an optical element comprising a pattern of features configured to control a propagation of light incident on the coupling element.
Claims20
A monolithically integrated optical assembly comprising:
- a waveguide configured to receive light;
- a coupling element configured to couple light into the waveguide;
- and
- an optical element comprising a pattern of features configured to control a propagation of light incident on the coupling element,
- wherein the optical element is configured to control an angle at which light is incident on the coupling element and wherein the optical element is configured to control a focus of light incident on the coupling element,
- wherein the optical element is configured to direct light toward the coupling element at an angle of incidence of 10° or less,
- wherein the optical element is disposed over the coupling element so as to overlap only a portion of the coupling element.
