Experimental demonstration of two methods for controlling the group delay in a system with photonic-crystal resonators coupled to a waveguide

We measure the group delay in an on-chip photonic-crystal device with two resonators side coupled to a waveguide. We demonstrate that such a group delay can be controlled by tuning either the propagation phase of the waveguide or the frequency of the resonators.
