Generalized fast, slow, stop, and store light optically within a nanoring resonator

We propose a remarkably simple system of an all optical system that can be used to fast, slow, stop, and store light coherently. The proposed system consist two micro and a nanoring resonators that can be integrated into a single system, which can be used to overcome the problem of bandwidth delay constraints with small group velocities. The large bandwidth is generated by a soliton pulse within a Kerr type nonlinear medium where an all optical adiabatic and reversible pulse bandwidth compression can be performed. The balance between dispersion and nonlinear lengths of the soliton pulse exhibits the soliton behavior known as self-phase modulation, which introduces the optical output (i.e., gain) constant, which means that light pulse can be trapped, that is, stopped coherently within the nanowaveguide. The time independent optical gain is stored within the nanoring device, which is available for read only memory use. The memory time of 1 ps is achieved. © 2009 Wiley Periodicals, Inc.
