“…Impurity-induced disordering using Zn or Si is a widely used QWI process, and the first reported NAM laser [2], and more recent reports [3,4] used these impurities. However, Zn and Si are electrically active, so their use leads to free-carrier absorption losses and current leakage, both of which are undesirable in high-performance NAMs.…”

“…N 0 is also temperature-dependent, which decreases sharply with the falling of temperature. 29,30 Therefore, the SOA operating at lower temperature may exhibit an excellent performance. Figure 10 presents the receiver sensitivity after 20 km at BER = 10×10 − 9 for the mm-wave system based on NRZon-off keying (OOK) is higher than the receiver sensitivities of the mm-wave systems base on other formats, because the NRZ-OOK code has the most excellent dispersion tolerance in the four types of formatted codes.…”

“…[28][29][30][31] Because at the transparent point the separation of the quasi-Fermi energies is equal to the energy of the incident photon, the transparent condition is a function of the incident wavelength. 29,30 The value of N 0 will decrease when the wavelength approaches the bandedge toward the long wavelength side. N 0 is also temperature-dependent, which decreases sharply with the falling of temperature.…”

Photonic millimeter wave (mm-wave) signal generation employing a differential Mach-Zehnder modulator (DMZM) and a semiconductor optical amplifier (SOA) is proposed and evaluated by theoretical analysis and simulation. This paper presents the theoretical study of the generation of a co-polarized and phase-locked dual-pump for four-wave mixing and optical mm-wave signal, the propagation of the optical mmwave signal in single mode fiber, and the coherent demodulation of the electrical mm-wave signal at the base station. Performance analysis and optimization design of the proposed scheme are conducted via simulations. The generation of mm-wave signals at 30, 40, and 60 GHz is simulated and analyzed. The influence of SOA and the input optical signal on the mm-wave generation and transmission is investigated. Simulation results present useful insight for the practicality of photonic mm-wave signal generation and distribution in the next-generation access network.

“…Smoothened QW boundaries induce larger band gap and resultant blue shift of PL peaks. There are several techniques for QWI, such as impurity-induced disordering (IID) [12], impurity-free vacancy disordering (IFVD) [13,14], ion irradiationinduced disordering [15,16], plasma damage-induced intermixing [17,18], and laser-induced disordering [19]. Most of QWIs, except the ion irradiation-induced disordering, are atom diffusion-based technologies and they are hardly applicable for LD structures with a thick cladding layer (>1 mm) [20,21].…”
