概要

We investigate numerically zero-gain Brillouin slow light in a single mode tellurite fiber. The effects of the bandwidth ratio $\beta$ between the loss and gain on the pulse delay and widening are discussed in detail. Our simulated results show that, the time delay in 200 m long tellurite fiber can reach 255 ns and the corresponding widening factor of the input pulse (pulse width $\sim$ 20 ns) is less than 3 when the pump power is fixed at 1194.6 mW and $\beta=10$. The limitation of zero-gain slow light system is also discussed.
