Abstract:
1. A method for singulating hybrid integrated photonic chips, wherein the method comprises: defining trenches from a front surface of a substrate extending partially through a thickness of the substrate; coupling photonic integrated circuits to the substrate, wherein a given photonic integrated circuit has a front surface facing the front surface of the substrate, and wherein the given photonic circuit at least partially overlaps a given trench; coupling a carrier to the front surface of the substrate; reducing the thickness of the substrate from a back surface of the substrate; coupling a support mechanism to the back surface of the substrate; removing the carrier from the front surface of the substrate; and singulating the hybrid integrated photonic chips by removing the support mechanism from the back surface of the substrate, wherein a given hybrid integrated photonic chip includes a portion of the substrate and one of the photonic integrated circuits.
