“…Furthermore, the optical fiber has low power losses and better bandwidth utilization, and it is immune to electromagnetic interference. 12,13 Nonlinear distortions caused by electrical-to-optical and optical-to-electrical conversions and fiber dispersion cause nonlinear distortions in RoF transmissions. 14,15 While launching longer wavelength sideband signals, the resonant frequency Multi Resolution Modulation (MRM) is decoded with OFDM signal.…”

Summary In heterogeneous access network, Multiple‐Input Multiple‐Output (MIMO) radio‐over‐fiber (RoF) system is an efficient approach for multiple signal transmission with low cost and complexity. The performance of RoF fronthaul system in MIMO system will be varied with different nonlinear effects. By adjusting various transmission parameters, such as the input signal power or the laser bias current, the nonlinear impacts produced by the RoF system can be reduced. In this paper, a novel algorithm Improved Aquila Optimization (IAO) is proposed to optimize transmission circumstances of MIMO RoF system. It determines the appropriate bias current for both lasers and Radio Frequency (RF) signal power in a short period. The input signals are wavelength multiplexed with Intensity Modulation and Direct Detection (IM/DD) applied. The carrier as well as transmission frequency is governed by the MIMO‐Long‐Term Evolution (LTE) standard. The proposed system is implemented in MATLAB, and the performance is evaluated. The experimental results show that fast convergence and trade‐off between noise and nonlinearity are obtained with varying bandwidth. In the experimental scenario, the maximum Error Vector Magnitude (EVM) of 1.88, 3.14, and signal‐to‐noise ratio (SNR) of 3.204, and 2.698 was attained for both quadrature phase shift keying (QPSK) and quadrature amplitude modulation (QAM) modulation. [Correction added on 24 April 2023, after first online publication: the SNR values were corrected in the preceding sentence.] For 100 iterations, the processing time was reduced to 0.137 s. When compared with the conventional state‐of‐the‐art approaches, the accuracy and computational complexity of the proposed approach are improved.

“…Multiwavelength emission has been achieved using different fiber laser sources, including erbium-doped fiber laser (EDFL) [1][2][3][4][5], Raman lasers [6,7], and hybrid Raman and erbium-doped fiber [8,9]. However, the homogeneous line broadening and mode competition were the main challenges for generating a stable dual-and multiwavelength operation at room temperature, even with our recent research work on dual-wavelength lasing for 5G and LiDAR applications [10][11][12][13]. In addition, many other techniques have been used for improving the EDFL multiwavelength stability, such as cooling the EDF down to cryogenic temperature [14], using a specially designed twin-core EDF [15], using frequency shift feedback [16], using intensity-dependent loss mechanisms like nonlinear fiber loop mirror (NOLM) [17], nonlinear polarization rotation (NPR) [18], incorporating EDF with SOA [19,20].…”

Tunable multiwavelength fiber lasers based on semiconductor optical amplifiers (SOA) have received attracting interest due to their wide prospective applications in dense division multiplexing (DWDM) systems and optical sensing. Using an SOA in a nonlinear optical loop mirror (NOLM), we demonstrate up to 13 lasing peaks by controlling the pump current and the polarization controller. At maximum pump current (450 mA), the emitted multiwavelength is between 1550 nm and 1572 nm with a wavelength spacing of 1.87 nm and 3 dB output linewidth of 0.8 nm with an output power of −7 dBm and 27 dB optical signal-to-noise ratio (OSNR). The multiwavelength output power and multiwavelength peak stability are investigated, and it was found that the power fluctuation of each multiwavelength line is less than 0.2 dB. In addition, by adjusting the polarization controllers (PCs) and SOA temperature, we obtained a tunable multiwavelength emission. The proposed fiber laser offers advantages such as simple structure, low loss, and long-time stable and multiwavelength emission.
