Abstract :

In the framework of the nonlinear waveguide, we investigate propagation of solitons with in optical ring resonators. We show how the complicated nonlinear interplay slow light solitons in the MRRs to the possibility to create optical buffer. Dynamical control over slow-light solitons is realized via a controlling field generated by bright soliton. We provide an analytical description for the nonlinear dependence of the velocity of the signal on the controlling field. The buffering effect is achieved by slowing the optical signal using an external control light source to vary the dispersion characteristic of the medium via optical ring resonators. We present a theoretical and simulation investigation of the criteria for achieving slow light in semiconductor microring resonators. The output signal shows the rate of delay time by propagation through the semiconductor optical ring resonators to used optical buffer.
