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.
