Fig. 5From: Strip-loaded nano-photonics on horizontal slot waveguideComparison of the spectra and in-plane mode distributions in the case of (top to bottom) a fully open Bragg grating (blue), a rounded corrugated sidewall grating (red), and a row of circular holes (green) in the center of the waveguide. The period is kept constant, p = 470 nmBack to article page
