Classification: CPC G  H | IPC G  H

Claim 18:
19. A method, comprising:
forming a first dielectric layer carried by a first substrate;
forming a grating coupler and a waveguide over the first dielectric layer;
forming a second dielectric layer covering the grating coupler, the waveguide and the first dielectric layer;
patterning the first dielectric layer and the second dielectric layer until the first substrate is revealed;
transfer-bonding the grating coupler, the waveguide and the first dielectric layer from the first substrate to a carrier;
providing a second substrate comprising an optical reflective layer; and
bonding the grating coupler, the waveguide and the first dielectric layer carried by the carrier with the optical reflective layer.
