We firstly demonstrate a simple system of fast light generation using a soliton pulse circulating in the integrated micro ring devices. Using such a system, the attosecond pulse and beyond can be easily generated. Simulation results obtained have shown that the generation of a very narrow full-width at half maximum (FWHM) and sharp tip are achieved. In principle, light pulse known as a soliton pulse is generated and input into a three-stage micro ring resonator, where the ring radii are within the ranges from 5 to 15 μm. With some selected parameters such as ring radii, coupling coefficients and nonlinear refractive indices, the extremely short pulse is generated, which means fast light is generated from ns to zs and beyond by using the simple system.
