All-optical diode action with quasiperiodic photonic crystals
نویسنده
چکیده
We theoretically investigate the possibility of realizing a nonlinear all-optical diode by using the unique features of quasiperiodic 1D photonic crystals. The interplay between the intrinsic spatial asymmetry in odd-order Thue-Morse lattices and Kerr nonlinearity, combined with the unconventional field localization properties of this class of quasiperiodic sequences, gives rise to sharp resonances that can be used to give a polarization-insensitive, nonreciprocal propagation with a contrast close to unity for low optical intensities.

We theoretically investigate the possibility of realizing a nonlinear all-optical diode by using the unique field-localization properties (known as Anderson-Kohmoto localization) of Thue-Morse quasiperiodic 1D photonic crystals. The interplay between the intrinsic spatial asymmetry in odd-order Thue-Morse lattices and Kerr nonlinearity gives rise to sharp resonances of perfect transmission that...
