Abstract:Slow light (SL) states corresponding to wavelength regions near the bandgap edge of grated structures are known to show strong eld enhancement. Such states may be excited efciently by well-optimised adiabatic transitions in grating structures, e.g., by slowly turning on the modulation depth. To study adiabatic excitations, a detailed investigation in 1D is performed to obtain insight into the relation between the device parameters and properties like eld enhancement and modal reection. The results enable the design of an adiabatic device for efcient excitation of SL states in 1D, and may be the basis for further research on 2D and 3D photonic crystals.
