Low-noise figure C+L-band EDFA with a preamplifier and an improved double-pass L-band amplifier

We proposed and demonstrated a new configuration of the low noise figure C+L- band erbium- doped fiber amplifier. In the configuration, a preamplifier is used to reduce the noise figure, and an improved double-pass configuration with a fiber Bragg grating was employed to enhance the L-band gain and while to reduce the noise figure. The experiment demonstrated that the noise figure in the new broad-band amplifier was improved by ~2 dB, and the gain was enhanced up to above 25dB over the region from 1525 to 1605nm.
