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

Claim 11:
12. An optical apparatus comprising:
a substrate transparent to incident light; wherein the substrate includes opposed first and second major surfaces;
a first waveguide disposed within the substrate;
wherein the first waveguide includes multiple first beam splitting surfaces disposed in a sequence to receive incident light and to transmit a portion of the incident light to a next first beam splitting surface in the sequence and to reflect a portion of the incident light toward the first major surface on a first lightpath;
a second waveguide disposed within the substrate;
wherein the second waveguide includes multiple second beam splitting surfaces disposed in a sequence to receive incident light and to transmit a portion of the incident light to a next second beam splitting surface in the sequence and to reflect a portion of the incident light toward the first major surface on a second lightpath;
wherein the first and second waveguides are disposed within the substrate in a non overlapping arrangement such that no light reflected by a second beam splitting surface of the second waveguide passes between and through a pair of first beam splitting surfaces of the first waveguide and such that no light reflected by a first beam splitting surface of the first waveguide passes between a pair of second beam splitting surfaces of the second waveguide, wherein the first waveguide abuts the second waveguide in the substrate, and
wherein the first lightpath and the second lightpath do not intersect.
