Slow light is theoretically and experimentally demonstrated in a phase-shifted multichannel fiber Bragg grating (FBG) which has the ability not only to produce the slow-lights in multiple channels simultaneously but also to make the delay time tunable by changing the magnitude of the inserted phase shift. Phase shift is introduced into a phase-only sampled 51-channel FBG by utilization of a small piezoelectric transducer (PZT). On the other hand, the group delay of each channel can be further enhanced by incorporating stimulated Brillouin scattering (SBS).
