“…We assumed the same values of A 1, A 2, B 1 and B 2 as for an AlGaAs/GaAs bulk SOA [9][10][11][12][13][14]. Generally, the fast Fourier transformation BPM (FFT-BPM) is used for analysis of the optical pulse propagation in optical fibres by successive iterations of the Fourier transformation and the inverse Fourier transformation.…”

“…This analysis is based on the MNLSE considering the non-linearities in SOA, such as self-phase modulation (SPM), two-photon absorption (TPA), group velocity dispersion (GVD), carrier depletion (CD), carrier heating (CH), spectral-hole burning (SHB), gain spectrum dynamics, and gain saturation in the SOA [5,7]. To solve the MNLSE, the finite-difference beam propagation method (FD-BPM) is used because of its short convergence time and excellent accuracy of the simulated results [8][9][10][11][12][13][14][15][16]. For simulation of pulse propagation with small propagation steps, FD-BPM is considered as the best method compared to others [8][9][10][11][12][13][14].…”

a b s t r a c tThis paper presents the pulse propagation and gain saturation characteristics for different input optical pulse shapes with different energy levels in semiconductor optical amplifiers (SOAs). A finite-difference beam propagation method (FD-BPM) is used to solve the modified nonlinear Schrödinger equation (MNLSE) for the simulation of nonlinear optical pulse propagation and gain saturation characteristics in the SOAs. In this MNLSE, the gain spectrum dynamics, gain saturation are taken into account those are depend on the carrier depletion, carrier heating, spectral hole-burning, group velocity dispersion, self-phase modulation and two photon absorption. From this simulation, we obtained the output waveforms and spectra for different input pulse shapes considering different input energy levels. It has shown that the output pulse shape has changed due to the variation of input parameters, such as input pulse shape, input pulse width, and input pulse energy levels. It also shown clearly that the peak position of the output waveforms are shifted toward the leading edge which is due to the gain saturation of the SOA. We also compared the gain saturation characteristics in the SOA for different input pulse shapes.

“…In particular, SOAs have the capability to be integrated with other InP (Indium phosphide)-based optical components, which makes it more attractive to implement very high compact optical systems. Extensive theoretical studies and analysis of SOA-based optical systems have shown that they can be used for several applications, such as compact SOA-based laser rangefinders [48], optical pulse delay discriminators [49,50], and optical and logic gates [51] for high-speed optical communications by exploiting four-wave mixing [52,53]. In addition, note that when the SOAs are used in a bidirectional fiber ring resonator structure, such as the proposed one, they do not require extra optical components, for instance, optical isolators and optical circulators; as a result, they are easy to integrate with other optical components for compact fiber laser systems.…”

A simple, stable and inexpensive dual-output port widely tunable semiconductor optical amplifier (SOA)-based fiber compound-ring laser structure is demonstrated. This unique nested ring cavity enables high optical power to split into different branches where amplification and wavelength selection are achieved by using low-power SOAs and a tunable filter. Furthermore, two Sagnac loop mirrors, which are spliced at the two ends of the compound-ring cavity not only serve as variable reflectors but also channel the optical energy back to the same port without using any high optical power combiner. We propose and discuss how the demonstrated fiber compound-ring laser structure can be extended in order to achieve a high power fiber laser source by using low power optical components, such as N × N couplers and (N > 1) number of SOAs. A coherent beam-combining efficiency of over 98% for two parallel nested fiber ring resonators is achieved over the C-band tuning range of 30 nm. Optical signal-to-noise ratio (OSNR) of +45 dB, and optical power fluctuation of less than ±0.02 dB are measured over three hours at room temperature.
