  • NANOIMPRINTED PHOTONIC INTEGRATED CIRCUITS
    Publication number: 20240027687
    Abstract: A method of making a photonic integrated circuit (PIC) is provided. The method comprises depositing a functional resist material layer over a substrate, disposing and pressing a stamp with a plurality of nanopatterns into the functional resist material for a period of time, and removing the stamp from the functional resist material to provide nanofeatures that are inverted versions of the nanopatterns, wherein the nanofeatures form one or more optical elements.
    Type: Application
    Filed: October 2, 2023
    Publication date: January 25, 2024
    Inventors: MARK WILLIAM KNIGHT, STEPHANIE ROXANE SANDOR-LEAHY, LAKSHMINARAYANAN RAVI NARASIMHAN
