Staff View: Fast and slow light generated by surface plasmon wave and gold grating coupling effects

Fast and slow light generated by surface plasmon wave and gold grating coupling effects

We present here the results of a simulation of the effect of gold and graphene coatings on silicon micro-ring resonators. We studied the effect of different radii of graphene on the time delay, from which one an interesting aspect of light pulse behaviors, such as fast light, was numerically investi...
