Claim 5:
6. A non-transitory machine-readable medium storing instructions that when executed by a processor performs a method for generating a physical layout for a grating coupler integrated in a photonically-enabled circuit, the method comprising:
receiving a photonically-enabled integrated circuit design;
receiving a parametrized wavelength of an optical beam, a parametrized first refractive index of the grating coupler, and a parametrized second refractive index of a cladding layer;
receiving a parametrized taper length of the grating coupler, a parametrized width of the grating coupler, a parametrized grating length of the grating coupler, and a parametrized incident angle of the optical beam incident onto the grating coupler;
generating connection routing layouts for the grating coupler placed on the semiconductor substrate;
generating a physical layout for the grating coupler based on the received parametrized wavelength, the parametrized first refractive index, the parametrized second refractive index, the parametrized taper length, the parametrized width, the parametrized grating length, and the parametrized incident angle, wherein the generating of the physical layout is according to a predefined model; and
outputting the physical layout of the grating coupler for manufacturing under a semiconductor fabrication process.
