<span>This paper shows dual stage thulium-doped fiber amplifiers (TDFAs) that use a pump power distribution technique. Simulations were done with signals ranging from 1975 nm to 2000 nm using the OptiSystem v.13 software. The results required were gathered from the software. The results of gain, noise figure, optical signal-to-noise ratio (OSNR) and output power were obtained. The highest gain and lowest noise figure results were achieved for the double pass dual stage TDFA configuration with values of 19.85 dB and 5.58 dB respectively, followed by the single pass dual stage TDFA. The OSNR and output power performances were also better for the double pass dual stage TDFA, obtaining 57.12 dB and 19.55 dBm respectively. This study shows that thulium can be used in the 2 µm region as an active gain medium and the dual stage architecture and distributed pumping technique proves to be effective techniques to obtain the desired results. Experimental work will be done in the future with the simulated results used as a reference.</span>

The optical amplification performance of the proposed Zirconia Yttria Aluminum Erbium co-doped fiber (Zr-EDF) was compared for two different pumping schemes; 1480 and 980[Formula: see text]nm. An efficient [Formula: see text]-band amplifier was achieved using 3[Formula: see text]m length of Zr-EDF while 1480[Formula: see text]nm pumping is found to provide higher attainable gain and better noise figure as compared to 980[Formula: see text]nm pumping. At a pumping wavelength of 1480[Formula: see text]nm and an input signal power of [Formula: see text]10[Formula: see text]dBm, the proposed amplifier provides a relatively flat-gain of about 13.3[Formula: see text]and 17.3[Formula: see text]dB with single-pass and double-pass configuration, respectively, where the gain variation was less than 1[Formula: see text]dB within a wavelength region of 1560–1600[Formula: see text]nm. The noise figures of the proposed Zr-EDFA were maintained below 8 and 14.5[Formula: see text]dB for single-pass and double-pass arrangement, respectively, within the flat-gain region. Compared to the conventional amplifier configured with silica based erbium-doped fiber amplifier, the proposed Zr-EDF-based amplifier achieves a higher and flatter gain and lower noise figure at [Formula: see text]-band region even though it uses a shorter length of gain medium.

Flat Gain

In this paper, we proposed a flat-gain and wide-band erbium doped fiber amplifier (EDFA) using two chirped fiber Bragg grating (CFBG) in serial configuration for double-pass operation. The amplifier consists of two sections of Erbium-doped fiber (EDF) operating in C-band and L-band respectively. A CFBG is used in each section to reflect the amplified signal back to the active area so that the overall gain spectrum can be enhanced and flattened. It is also observed that the gain of the amplifier produces a relatively higher gain with the Bismuth-based EDF (Bi-EDF) in the first stage compared to that of silica-based EDF (Si-EDF), especially in a longer wavelength region. The small signal gain of more than 19 dB is obtained within a wavelength region from 1545 to 1605 nm by the use of Bi-EDF with a small noise figure penalty. With a Si-EDF, the flat gain spectrum is observed within a wavelength region ranging from 1535 nm to 1605 nm with a gain variation of less than 2 dB at input signal of 0 dBm. This shows that the proposed serial double-pass amplifier may find its broad applications in wavelength division multiplexing long-haul systems as well as local optical networks.
