Slow-light and evanescent modes at interfaces in photonic crystal waveguides: optimal extraction from experimental near-field measurements

Ha, Sangwoo; Spasenović, Marko; Sukhorukov, Andrey; White, Thomas P.; de Sterke, C. Martijn; Kuipers, L. (Kobus); Krauss, Thomas F.; Kivshar, Yuri

Description

We develop a systematic approach for simultaneous extraction of the dispersion relations and profiles of multiple modes in periodic waveguides though a special global optimization procedure applied to near-field electric field measurements in the waveguide plane. We apply this method to perform in-depth analysis of experimental data on wave propagation close to an interface between waveguide sections with different dispersion characteristics, and we successfully identify several modes...[Show more]
