Abstract
Embodiments of the disclosure provide an integrated circuit (IC) structure, including an absorber layer separated from an optical grating coupler by a cladding material. The absorber is positioned to receive light reoriented through the optical grating coupler.
Claims20
An integrated circuit (IC) structure, comprising an absorber layer separated from an optical grating coupler by a cladding material, wherein the absorber layer is positioned to receive light reoriented through the optical grating coupler.
An integrated circuit (IC) structure, comprising:
- an optical grating coupler coupled to an optical medium, wherein the optical grating coupler is configured to reorient light from the optical medium;
- and
- an absorber layer above the optical grating coupler, wherein at least a portion of a cladding material vertically separates the absorber layer from the optical grating coupler.
A method comprising:
- reorienting light from an optical medium in an optical grating coupler through a cladding layer;
- and
- absorbing the reoriented light in an absorber layer above the optical grating coupler, wherein at least a portion of a cladding material vertically separates the absorber layer from the optical grating coupler.
