Patent ID: 8351742

Claim:
A method of embedding a photonic sensor in metal, the method comprising: depositing at least one first optically insulating layer on a substrate; depositing and patterning at least one waveguide material on the first optically insulating layer to define the photonic sensor; depositing and patterning at least one second optically insulating layer over the photonic sensor; depositing at least one first metal layer over the at least one second optically insulating layer; etching the substrate to free the first and second optically insulating layers, the photonic sensor, and the at least one first metal layer from the substrate so as to expose a surface of the at least one first optically insulating layer; depositing at least one second metal layer over the exposed surface of the at least one first optically insulating layer so as to substantially embed the photonic sensor and first and second optically insulating layers between the first and second metal layers.
