“…[12][13][14]. To increase the gain of the TDFA, in some studies, the ampli er parameters were changed [15][16][17][18][19][20], while in others, different pumping con gurations were used to excite all thulium ions [21][22][23][24][25][26]. In addition, in some research, the gain has been increased by adding a mirror or an optical circulator to the basic TDFA design with double-pass con gurations [27][28][29][30][31].…”

The main goal of designing a multistage fiber amplifier is to achieve higher performance for long-haul optical transmission systems. In this paper, multistage triple-pass (TP) TDFAs are represented. Three types of TP-TDFA are modeled, optimized, and compared in the S-band for next-generation fiber optical communication systems. First, to examine the performance of these 3 types of TP-TDFAs, signal power, pump power, thulium-doped fiber (TDF) length, and thulium ion concentration were optimized in the input signal at the 1469 nm wavelength, which gives the highest gain value in the S-band, respectively. Second, the input signals in the 1444–1499 nm band gap were amplified by using these specified optimized values in all designs. Gain and noise figure values of all three types were obtained and analyzed by plotting separately for easy comparison. At the end of the study, all results were evaluated and all types were compared to determine the best TP-TDFA.

“…To obtain a good gain and low noise figure in TDFA, there are some studies conducted by changing basic parameters such as TDF length, pumping power, and thulium ion density 13–16 . Another study method for the same purpose is the examination of various pumping methods 17–21 . To excite all thulium ions, dual‐stage designs and distributed pumping techniques are fulfilled 22 .…”

This study presents a comparison of three different S-band thulium-doped fiber amplifiers (TDFA) designs. The gain performances of the amplifiers are analyzed based on each scheme, separately. With −20 dBm input power, to provide ground-state and excited-state absorptions, the 1050 nm pump is used in all designs. The thulium-doped fiber (TDF) lengths are optimized for maximum gain by using the single parameter single result optimization of Optisystem 18.0 software. A reflector is integrated into the double-pass and dual-stage triple-pass TDFA to allow double propagation. Compared to double-pass TDFA, in dualstage triple-pass TDFA design, gain values increased without changing the stable bandwidth. 42.77 dB gain is demonstrated for two optimized TDF lengths; L1: 5 m and L2: 4.8 m, while noise figure values are higher than the other schemes. This comparison is important to show that the dual-stage triple-pass TDFA design could be suitable for obtaining higher gain in wider stable bandwidth in the fiber optic communication systems.
