Abstract

A method, system or device for configuring an optical coupling device including obtaining characteristics of an optical signal and ambient conditions for storage in memory, utilizing a processor for identifying an optimum effective subwavelength area refractive index and a grating period for the input signal and ambient characteristics stored in memory, and utilizing the processor for identifying a preferred filling factor for a transverse polarization.
