“…In this work we explore a bismuth-doped fiber as an active medium for signal amplification at 1651 nm. As previously reported in [18][19][20], bismuth-doped fiber amplifiers (BDFA) can provide high gain (20 dB and more) for a small signal (less than -10 dBm) over broad spectral region (between 1.6 µm and 1.8 µm). They can also be conveniently pumped at wavelengths around 1.55-1.56 µm using standard erbium/ ytterbium-doped fiber amplifiers.…”

“…They can also be conveniently pumped at wavelengths around 1.55-1.56 µm using standard erbium/ ytterbium-doped fiber amplifiers. However, previous studies were focused primarily on analyzing small-signal gains or noise figures [18][19][20]. When an application to gas sensing is considered, an important parameter is the output power level, not the gain itself.…”

Erbium doped fiber amplifiers play an important role in various applications, spanning from fiber communication to optical sensing. Unfortunately, their gain bandwidth is limited to telecom C-and L-bands (from 1530-1625 nm). The application of bismuth-doped fibers is a promising approach for optical signal amplification at longer wavelengths. In this paper, a bismuth-doped fiber power amplifier seeded with a 1651 nm single-frequency laser diode is presented and its performance is experimentally analyzed. This amplifier may be used to improve performance of systems for methane detection, e.g. those based on photoacoustic spectroscopy or in remote/stand-off configuration (methane has a molecular absorption line near to 1651 nm). Two configurations of the amplifier are demonstrated and in both cases an output power of more than 80 mW is obtained. Limitations of current design are discussed. The obtained results give good a perspective for simple and compact fiber amplifiers with output powers exceeding 100 mW in the spectral region of ~1630-1750 nm.

“…More recently, bismuth (Bi) has emerged as a promising dopant for fibre amplifiers. Depending on the core composition (silica, aluminosilicate, phosphosilicate, germanosilicate, and others), construction, and pumping wavelength(s), BDFAs can be used to offer gain across a wide range of spectral regions from 1150nm to 1800nm [10][11][12][13][14][15]. Recently, Melkumov et al demonstrated E-band transmission using a Bi-doped germanosilicate fibre amplifier to amplify a 10.6Gbit/s on-off keying (OOK) signal at 1440nm after transmission over an 80km length of non-zero dispersion shifted fibre [16].…”

Extension in the reach of 1.3m optical communication systems has traditionally been restricted by the availability of suitable low-noise fibre amplifiers. Addressing this challenge, we present the first repeatered wavelength division multiplexing (WDM) experiments using a bismuth-doped fibre amplifier (BDFA) that exhibits 8.4THz (50nm) of gain bandwidth in the O-band. WDM signals arranged either with coarse or dense wavelength spacings are transmitted over lengths of SMF-28e ranging between 100km and 140km.

At the present time, developing of autonomous laser systems requires increasing of the output power of the laser sources used in composition of those systems and at the same time reducing of the energy usage in the system. The possibility of increasing output peak power of pulsed laser sources by using the method of synchronous non-coherent beam combining in ring fiber-optic delay line is considered by authors. Objective of this work was estimating energy effectiveness of laser systems, which based on this method.General constructing method of the laser pulsed laser source with ring fiber delay line is considered, its block diagram and the general operating principle of similar systems are presented. Two versions of laser systems based on the described method of beam combining are presented: using an optical combiner and an optical switch; using fiber welding instead of a combiner and an optical switch. The graphical dependence of the energy effectiveness on the number of circulations in ring fiber-optic delay line is obtained for both versions of laser systems.As a result of the analysis of the considered devices operation, it was shown that considered systems allow to obtain increasing the peak power of a laser pulse without increasing the power supply, also the system, that use welded fi instead of the optical combiner, has greater effi than system with optical combiner.
