Abstract

The parameters of Er3+-doped fiber which optimize the signal gain of a fiber amplifier pumped by a 1.48-μm laser diode are theoretically determined using the rate equation for a three-level laser system. The basic parameters specified are the relative-index difference and the cutoff wavelength. The optimum cutoff wavelength of a completely Er3+-doped core fiber with a step-index profile is 0.8 μm regardless of the value of the relative-index difference. The optimum cutoff wavelength depends on the Er3+-doped area radius.
