Nonlinear all-optical modulator based on non-Hermitian PT symmetry
文献摘要：
All-optical modulators with ultrahigh speed are in high demand due to the rapid development of optical inter-connection and computation.However,due to weak photon-photon interaction,the advancement of all-optical modulators is consequently hampered by the large footprint and high power consumption.In this work,the enhanced sensitivity around an exceptional point(EP)from parity-time(PT)symmetry theory is initiatively introduced into a nonlinear all-optical modulator design.Further,a non-Hermitian all-optical modulator based on PT symmetry is proposed,which utilizes the large Kerr nonlinearity from indium tin oxide(ITO)in its ep-silon-near-zero(ENZ)region.The whole system is expected to operate around EP,giving rise to the advantages of nanoscale integration and large modulation depth.This presented modulator with high efficiency and high-speed all-optical control can be commendably extended to the design methodology of various nanostructures and fur-ther prompt the development of all-optical signal processing.
