Abstract
A microLED may be used to generate light for intra-chip or inter-chip communications. The microLED, or an active layer of the microLED, may be embedded in a waveguide. The waveguide may include a lens.
Claims14
An optical coupling arrangement for an optical communication system, comprising:
- a microLED on a substrate, the microLED having a top surface and a bottom surface with an active layer therebetween;
- a waveguide on the substrate, the microLED being at least partially within the waveguide;
- a reflector on at least a portion of the waveguide, the reflector positioned to reflect light from the microLED down an axis of the waveguide;
- and
- a lens within the waveguide and in an optical path between the microLED and the reflector, the lens separated by one focal length from the active layer of the microLED.
