Abstract
Disclosed herein are a photonic integrated circuit (PIC) including an edge coupler (EC) and method thereof. In some embodiments, the EC is optically coupled to a first waveguide at an inner end of the EC. In some embodiments, the PIC is in contact with an optical fiber at an outer end of the EC. The EC may include a plurality of waveguide cores located on a plurality of waveguide layers. The waveguide cores of the plurality of waveguide cores are located apart from each other and configured to adapt a mode size of a beam of light between a larger mode size at the outer end of the EC and a smaller mode size at the inner end of the EC.
