Pr+-doped fluoride fiber amplifiers: optimum design considerations
Date of Original Version
Waveguide parameters for Pr+-doped fluoride fiber amplifiers have been optimized for low and moderate values of relative refractive index difference. A cut-off wavelength of 750 nm gives maximum gain for NA = 0.1 and 0.2. A pump reflecting mirror etched at the output end of the amplifier gives higher gain at smaller lengths (≈ 1/3) in both the small and large signal regimes.
