The double-pass erbium-doped zirconia fiber amplifier (EDZFA) is proposed and demonstrated to provide a wide-band amplification as well as flat-gain operation in both the C-and L-band regions using only a single-gain medium. The proposed amplifier utilizes an erbium-doped zirconia fiber (EDZF) with

## Abstract A novel reflection L‐band erbium‐doped fiber amplifier, based on a fiber loop mirror, is constructed. This amplifier reflects the backward ASE to the EDF as a secondary pumping source. A gain of 30 dB (an increase of 6 dB) is obtained, compared to the forward‐end‐pumped EDFA in the rang
## Abstract We present a single‐pass L‐band erbium doped fiber amplifier (EDFA) based on a large mode area (LMA) fiber. A single transverse mode is maintained through restricted mode launch. Pump light near 974 nm is sent into the core and has high spatial overlap with the signal beam, helping to p
