We propose a novel design of optical buffer to generate slowlightbasedondelaytime.Intheframeworkofthenonlinearwaveguide,weinvestigate propagation of solitons through microring resonators. Dynami-cal control over slow-light solitons is realized via controlling fields gener-ated by bright soliton and Gaussian pulse. The nonlinear dependence ofthe velocity of the signal on the controlling field is analytically described.The buffering effect is achieved by slowing the optical signal using anexternal control light source to vary the dispersion characteristic of themedium via microring resonators. A graphical approach with a signalflow graph method is used to derive the optical transfer functions in
