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 preserve single mode propagation. Up to +27 dB of pump power limited small signal gain (30 μW signal input) with a noise figure (NF) near 4.4 is achieved in a relatively short fiber[b]. © 2008 Wiley Periodicals, Inc.

## 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 A novel L‐band fiber amplifier comprised of two sections of erbium‐doped fiber (EDF) and an optical reflector is used to enhance power‐conversion efficiency (PCE). We also examine how an optical amplifier can be used without an optical reflector while nonetheless making effective use of

An erbium-doped fiber amplifier (EDFA) for S-band signal amplification is designed by using a depressed cladding erbium-doped fiber (DC-EDF). The fiber's characteristics are described in terms of the effects of the fiber spooling diameter on the amplifier's performance. In this experiment, the spool

## Abstract A two‐stage short‐wavelength‐band erbium‐doped fiber amplifier (S‐band EDFA) is demonstrated using a depressed‐cladding erbium‐doped fiber (EDF). The EDF has a fundamental‐mode cutoff wavelength of about 1525 nm in order to suppress amplified spontaneous emission at the longer wavelengt

## Abstract Gain clamping in a long‐wavelength‐band erbium‐doped fiber amplifier (L‐band EDFA) using a C/L‐band WDM coupler is demonstrated. The gain for the amplifier is clamped at 15.5 dB with a gain variation of less than 0.2 dB from input signal power ranging from −40 to −14 dBm with almost neg

## Abstract An actively mode‐locked fiber laser (AMLFL) based on the hybrid gain of a dispersion‐shifted fiber (as the Raman gain medium) and an Erbium‐doped fiber (EDF) is introduced. The fiber Raman gain mechanism can effectively suppress the gain competition of an EDF, which usually results into
