Abstract
At least a portion of an integrated circuit wafer includes at least one layer in which two or more waveguides are formed. A cavity is formed in the integrated circuit wafer. At least one die, comprising a photonic integrated circuit, has: at least one edge on which there are two or more optical mode defining structures in proximity to respective optical mode defining structures on at least one surface of the cavity, a bottom surface secured to a bottom surface of the cavity, and a top surface on which there is at least one metal contact.
Claims20
An article of manufacture comprising:
- at least a portion of an integrated circuit wafer that includes at least one layer in which two or more waveguides are formed;
- a cavity formed in the integrated circuit wafer;
- at least one die comprising a photonic integrated circuit, the die having
- at least one edge on which there are two or more optical mode defining structures in proximity to respective optical mode defining structures on at least one surface of the cavity,
- a bottom surface secured to a bottom surface of the cavity, and
- a top surface on which there is at least one metal contact.
A method comprising:
- forming two or more waveguides in at least one layer of an integrated circuit wafer;
- forming a cavity in the integrated circuit wafer;
- securing a die comprising a photonic integrated circuit within the cavity, the securing comprising
- aligning two or more optical mode defining structures on at least one edge of the die to respective optical mode defining structures on at least one surface of the cavity, and
- forming a bond between a bottom surface of the die and a bottom surface of the cavity;
- and
- forming an electrical connection between at least one metal contact on a top surface of the die to a portion of the integrated circuit wafer.
