“…In this scenario a CW laser has been used in place of VCSEL. The CW laser is the most widely used optical source in almost all communication networks due to its high emitting bandwidth which offers transmitting high data rates [25][26][27] . The performance of the PON system, using VCSEL source and the same PON system based on using CW laser is calculated.…”

Passive Optical Network (PON) is a promising 5G optical fiber network technology, that can enhance reliability data rate, and bandwidth saving. This simulation- based study investigates the feasibility of implementing a vertical cavity-surface emitting laser (VCSEL) optical source along with wavelength-division multiplexing (WDM) for designing a PON radio over fiber (RoF) system that can authorize multi-subscribers, users, to simultaneously use the same optical fiber for Front long-haul data transmission. Three scenarios are proposed: First, a VCSEL, and a Mach-Zehnder Modulator with a distinctive frequency are made accessible to every user in the PON system. Whereas, in the second scenario, a continuous wave (CW) laser is used to replace the VCSEL in the same PON. 16 users are multiplexed by a WDM and transmitted over a link length of 200 km. The system performance is, thus measured in terms of Q-factor, and it is revealed that the VCSEL-based system outperforms the system utilized CW laser to a distance of 150 km, with a maximum gain in the Q-factor of about 4.5. Both postulated systems are able to achieve a maximum transmission distance of 180 km with a minimum Q-factor of 6. Moreover, to minimize, the input current of around 1 mA and the system complexity, a third scenario is presented in which one VCSEL with 193.1 THz is shared among multiple users. The Q-factor performance is then simulated for up to 72 users, revealing that the minimum level of acceptable Q-factor has been maintained up to a link length of 180 km.

“…In the past few years, wavelength-tunable pulsed lasers have been in high demand in the fields of biomedical diagnostics [1] , laser spectroscopy [2] , and optical measurements [3] . Wavelengthtunable lasers can be selected at different wavelengths according to the needs of the actual application area and have such features as low cost, simple structure, and wavelength selectability.…”

Wavelength-tunable dissipative solitons and amplifier similaritons have been obtained by inserting all-fiber Mach-Zehnder interferometer (MZI) filters with different free spectral ranges (FSRs) in a Yb-doped mode-locked fiber laser. The MZI filter is fabricated by splicing one segment of seven-core fiber (SCF) between two segments of single-mode fibers. The bandwidth of the filter depends on the FSR of the modulated interference curve and consequently depends on the tapered fiber diameter. Inserting MZI filters with bandwidths in a fiber laser and applying a tensile strain on the tapered SCF, both wavelengthtunable dissipative solitons and amplifier similaritons have been obtained.
