“…It may be observed that our proposed amplifier design with optimized parameters has better performance as compared to the results of the past studies as mentioned in [5,[12][13][14]16]. There are few past studies in the literature [22,26,27] in which the authors have demonstrated higher peak gains and output powers as compared to the same in the proposed work. The design of the HDFA proposed in [26,27] is based on multi-stage pumping and the design of [22] exploits shared pump double-stage pumping while our optimized design is based on a single forward pump source and a single short piece of HDF.…”

“…The short piece of HDF is the most critical component in the proposed optimized design whose parameters greatly affect the performance of the HDFA. The parameters of HDF used in the simulation are shown in Table 2, which are offered by iXblue for their polarization maintaining Ho 3+ doped single clad silica fiber used in experimental work [22]. This fiber is nominally single-mode at 2.05 µm having V-number and mode-field diameter (MFD) of 2.45 and 8.6 µm, respectively.…”

In this paper, we address the performance optimization of Holmium doped fiber amplifier (HDFA) for optical communications in 2–2.15 μm wavelength range based on a single in-band forward pump source. The performance of the HDFA is analyzed with the help of theoretical simulations by considering an optimized length of Holmium doped fiber (HDF), doping concentration of Ho3+, and pump power. The impact of signal wavelength and power on gain, amplified spontaneous emission (ASE) noise, and noise figure (NF) of the amplifier is investigated. Furthermore, we investigate the variations in the gain of the amplifier, its output power, and NF by varying the power and wavelength of the pump source. After optimizing the parameters of the amplifier, the peak gain observed is around 56.5 dB, the 3 dB saturated output power obtained is 33.3 dBm, and the output power is 3 W at signal wavelength of 2.0321 μm for HDF having an optimized length of 12 m and pump power of 3.5 W. Minimum NF of around 8.2 dB is observed at 2.0321 μm for signal power of −5 dBm. The impact of ion-ion interaction on the performance of HDFA is also investigated. A reduction of 24.2 dB and 0.051 W is observed in peak gain and output power of HDFA, respectively by considering the ion-ion interaction.

“…We note that Tm-doped fiber lasers can readily be engineered to produce multiwatt output powers over a wavelength band spanning 1800-1980 nm and more. To verify our hypotheses in a systematic way, we studied through simulations [10][11][12] the performance of a 3 m long Ho-doped amplifier in Fig. 2 as a function of pump wavelength.…”

We report the design and performance of medium slope efficiency (64%) Holmium-doped fiber amplifiers (HDFAs) with novel alternative in-band pump wavelengths in the 1720-2000 nm spectral region. We demonstrate through simulations that pump wavelengths of 1840-1860 nm can yield significantly improved output power, gain, and optical-optical conversion efficiency compared to the previous technical and industry standard pump wavelength of 1940 nm. Our simulations are verified by experimental data.

“…Output from a multi-watt fiber laser P1 at 1941 nm is split by coupler C1 (30%/70%) and is sent to both F1 and F2 via the WDMs. Complete evaluation of the Ho-doped preamplifier is discussed in forthcoming papers [5,6]. The preamplifier output provides the signal input to power amplifier F3, a 5.0 m length of double clad PM Tm-doped fiber (Coherent-Nufern PM-TDF-10P/130-HE).…”
