“…The schematic structure of the proposed self-start multi-wavelength laser source for wireless networks is shown in Figure 1. The demultiplexer selects two wavelengths from the multi-wavelength laser source for each channel [17]. The desirable data streams are modulated onto the selected wavelengths by the RSOA.…”

“…The center frequency of the signal is located at 9.953 GHz and the eye diagram is also clear. The RF signal is generated by the two-tone interference method [17]. The SNR is over 20 dB, which may support future wireless broadband access applications.…”

“…Thus, the goals of transmitting and receiving more data as enhanced Mobile Broadband (eMBB), interconnecting millions of devices at once by means of massive machine type communication (mMTC), and increasing responsiveness by ultra-reliability and low latency communication (URLLC) for fifth-generation (5G) new radio (NR) next-generation communication systems are considerably studied [6][7][8][9][10][11][12][13]. The radio-over-fiber (RoF) technique, which can generate and deliver millimeter-wave signals in the optical domain, is a good candidate for next-generation communication systems due to the advantages of fiber such as high capacity, low attenuation, lightweight, and being free from electromagnetic noise interference (EMI) [14][15][16][17][18]. In the RoF transmission system, the desired signal can be optically upconverted to a higher frequency band by means of selecting the specific wavelength.…”

The radio-over-fiber (RoF) technique has gained a lot of interest recently, as the millimeter-wave signals can be generated and delivered in the optical domain with the advantages of low attenuation, high capacity, and being free from electromagnetic noise interference (EMI). In this paper, we propose and experimentally prove a self-start multi-wavelength laser source based on a distributed feedback laser diode (DFB-LD) for the RoF transport system. The self-start multi-wavelength laser source generates stable laser power with less than 0.18 dB power fluctuation and exhibits good stability. In order to estimate the transmission performance, data is externally modulated onto the multi-wavelength by a reflective semiconductor optical amplifier (RSOA) and transmitted through single-mode fiber (SMF). The experimental result proves that the proposed RoF transport system achieves error-free transmission and clear eye diagrams.

“…In recent years, continuous-wave (CW) erbium-doped fiber (EDF) laser sources with broad tunability, constant single-longitudinal-mode (SLM) action and flat output spectrum have appealed to great interests, because of the promising applications of optical fiber communication, optical fiber sensor, microwave-photonic, and biophotonics [1][2][3][4]. To reach the wavelength selection in the EDF lasers, using the linear-and ring-based fiber cavities have been studied [5].…”

In this research, we present and study an erbium fiber laser with triplefiber-ring (TFR) scheme for continuous-wave (CW) wavelength-selection. The designed TFR not only can achieve single-longitudinal-mode (SLM) oscillation, but also can spread the tuning range from 1519.0 to 1583.0 nm covering C-and part of L-bands. Moreover, 0 dB power fluctuation can be obtained from 1523.0 nm to 1559.0 nm for flattened operation based on the compound-ring configuration. The Lorentzian laser linewidths of 22 to 29 kHz are also attained in the entire wavelength-tunable range.

Wavelength Switchable Mode-Locked Fiber Laser With Tapered Two-Mode Fiber

et al. 2019

We propose and demonstrate a wavelength switchable mode-locked Erbiumdoped fiber laser with carbon nanotubes for mode-locking and a tapered two-mode fiber (TTMF) based filter for wavelength selection. The TTMF based filter constructed with singlemode fiber-TTMF-single-mode fiber configuration, features smooth interference spectrum. It is attributed to that only two modes are involved into the interference in the specially designed TTMF, which is confirmed by both simulations and experiments. Moreover, the free spectral range (FSR) of the TTMF based filter can be arbitrarily chosen by controlling the taper diameter. Depending on the FSR of the TTMF based filter, the central wavelengths of the mode-locking operation of the Erbium-doped fiber laser based on carbon nanotubes can be switched between two wavelengths with FSR of 8.5 nm and three wavelengths with FSR of 3.1 nm, respectively. This fiber laser is flexible source for various applications.
