- Abstract
- The effect of deep subwavelength disorder in one-dimensional dichromic multilayer films on the optical transmission, localization length, and Goos-Flanchen shift around the critical angle is analyzed using sets of disordered multilayer films with different degrees of order metric tau. For each Gaussian-perturbed multilayer film designed by a Metropolis algorithm targeting the predetermined order metric tau, the numerically obtained localization length and transmission show excellent agreement with the recent theoretical analysis developed for disordered multilayer films, further revealing tau-dependence of the Goos-Hanchen shift across the critical angle. Emphasizing the role of deep subwavelength structures in disorder-induced transmission enhancement, our result thus paves the way toward the inverse design of a deep subwavelength disordered structural landscape for the targeted order metric tau or abnormal optical responses - including the Goos-Hanchen shift.
