All-optical switching of slow light in nonlinear Bragg grating coupler

Abstract

In recent years, it was demonstrated that the speed of light can be reduced dramatically in photonic-crystal waveguides with a periodic modulation of the optical refractive index. By making the light slower it becomes possible to introduce delays for the signal synchronization. Additionally, in the slow-light regime photon-matter interactions can be enhanced dramatically, allowing for all-optical control and manipulation of light1. At the same time, nonlinearity can support pulse self-trapping in the form of a gap soliton which profile remains undistorted during propagation2, overcoming the limitations of linear devices due to the dispersion-induced pulse broadening.
