A novel Er3+-doped honeycomb photonic bandgap fiber for highly efficient amplification

We present a numerical study of the guidance and amplification properties in an Er3+-doped honeycomb photonic bandgap fiber with down-doped core. Our analysis is based on a full-vector plane-wave expansion method and Runge-Kutta iterative algorithm. Overlap integrals between mode profiles and Er3+-doped region varies from 0.973 to 0.350 in guiding range of the fiber. The highly efficient amplifier can be designed by using this fiber.
