A slow/fast light device with a sealed size of has been demonstrated. Ultraslow propagation and superluminal propagation with group velocity values from 8.4 to are observed in a 3.86 cm long co-doped single-mode phosphate glass fiber. The dependence of pump power, modulation frequency, and wavelength on the slow/fast light effect in this fiber is investigated in detail. These results suggest that this compact slow/fast device is more suitable for all-fiber applications than those made by traditional methods.
