【 摘 要 】

We present a theoretical and experimental study on the effect of a control field over the temporal propagating characteristics of the signal field in a two-port device. We show that the time delay obtained by the two-port device for the signal field can be greatly modified by the employment of a control field, and therefore, this second input can be used to design devices with tunable group delay. This has been experimentally demonstrated by using a beam splitter plate as two-port system. Furthermore, we analyze the effect of the dual input for a fiber Bragg grating, where it is possible to significantly enhance the time delay with the appropriate control field.
