Abstract

To date rare-earth-doped fiber amplifier research has largely been aimed at producing efficient amplifiers for operation within either the third telecommunications window between 1.44 μm and 1.6 μm, or the second telecommunications window between 1.28 μm-1.34μm[1]. However, the relatively inexpensive nature of AlGaAs transmitters and Si detectors operating near 800 nm make operation within the first tele communication window, around 0.85 μm, an attractive possibility for short distance distribution, LAN or interconnection applications. A crucial component for such systems would be a practical and efficient amplifier operating in this window. In this work we report the demonstration of a 23 dB small signal gain at a wavelength of 850 nm in an erbium doped fluorozirconate fiber.
