Assignee: ADEIA SEMICONDUCTOR INC.
Field: Optics (Instruments)
Classification: CPC G | IPC F  G

Claim 9:
10. An optical apparatus comprising:
a substrate transparent to incident light; wherein the substrate includes opposed first and second major surfaces;
a first waveguide including multiple beam splitting elements, wherein the first waveguide emits light on a first lightpath;
a second waveguide including multiple beam splitting elements, wherein the second waveguide emits light on a second lightpath different from the first light path;
wherein the first and second waveguides are disposed in the substrate substantially equally distant from the first major surface, such that no light reflected by a beam splitting optical element of the first waveguide passes between and through beam splitting elements of the second waveguide, wherein the first waveguide abuts the second waveguide in the substrate,
wherein the first lightpath and the second lightpath do not intersect.
