Erbium-doped fiber amplifier in a reflective configuration with equalization of 1549.1 NM wavelength using a fiber bragg grating

Abstract

In this work we present an optical amplifier elaborated from Erbium-doped fiber (EDF) in reflective configuration. We can obtain bigger amplification with reflective configuration, because the signal is amplified twice in the same EDF. The signal reflection was carried out with a Fiber Bragg Grating (FBG). We use a DFB laser to equalization of 1549.1 nm wavelength. The amplifier was used successfully to investigate the operation of a nonlinear process in optical fibers.
