Anomalous reflection at the interface of binary synthetic photonic lattices

[摘要] We construct a binary synthetic photonic lattice theoretically by projecting two fiber loops' light intensity and adjusting the phase distribution precisely. By tuning the phase modulator, wave vector, and propagation constant of an effective waveguide, the interface's transmittance could be manipulated. Further study on light dynamics shows that the light pulse can achieve total reflection without diffraction and exchanges the light energy in two optical fiber loops completely when phase distribution and wave vector meet certain conditions. Our study may provide a new way to realize optical switches in optical interconnection and optical communication.
