From: Resonant Photonic States in Coupled Heterostructure Photonic Crystal Waveguides
Transmission spectra for the heterostructure waveguide in the direction of photon confinement, where the pump field is off (a) and on (b). For these plots, the outer photonic barriers were taken as d B = 5L B , the widths of the wells were d A = 15L A , and the central (nonlinear) barrier was taken as d C = 5L C . By applying the pump field, the system is switched between a double waveguide and a single, wider waveguide. This effectively switches the energy-splitting effect “off” or “on”
