Abstract

We theoretically examine two designs of single-mode (i) Er-doped tellurite and (ii) undoped tellurite photonic crystal fiber (PCF) for generation of slow light with tunable features based on stimulated Brillouin scattering. We obtained (i) Brillouin gain up to 91 dB and time delay of $\sim 145\mathrm{ns}$ at maximum allowable pump power of $\sim 775\mathrm{mW}$ in a 2 m Er-doped tellurite PCF and (ii) Brillouin gain up to $\sim 88\mathrm{dB}$ and time delay of $\sim 154\mathrm{ns}$ at maximum allowable pump power $\sim 21\mathrm{mW}$ in a 100 m undoped tellurite photonic crystal fiber. Simulated results clearly indicate that the doped tellurite PCF with Er enhances the maximum allowable pump power and comparable time delay can be obtained even with reduced photonic crystal fiber length. We believe that the carried out examination and simulation have potential impact on design and development of slow-light-based photonic devices applicable in telecommunication systems, enhancement of optical forces, and quantum computing.
