Surrogate modeling using coupled mode theory for accurate prediction of the optical response of long Bragg gratings

In this study, we propose a surrogate modeling approach that uses coupled mode theory (CMT) for accurate and efficient prediction of the reflectance and transmittance spectra of Bragg gratings. It is particularly useful for long structures (e.g. 2 mm), for which finite-difference time-domain (FDTD)...
