In this paper, titanium nitride nanoparticles were prepared in three methods, In the first method, titanium nitride nanoparticles were prepared by the Ball-mill method; in the second and third methods, the nanoparticles were synthesized by the sol-gel, and the co-precipitation methods. The samples were characterized by X-ray diffraction (XRD), UV-Vis spectroscopy, and scanning electron microscopy (SEM), for the study of structural, linear optical properties, and surface morphology study, respectively. The Z-scan technique was utilized to study the TiN nanoparticles nonlinearity. A change in nonlinear optical behavior with an increase in input pump power and concentration of the TiN nanoparticles was observed. Results showed that the TiN nanoparticles give new potentials in nonlinear optical applications. The nonlinear optical behavior of the TiN nanoparticles shifts from inverse saturation absorption to saturation absorption with increase of intensity.

In this study, the effects of hydrostatic pressure and temperature on nonlinear optical rectification (OR), second-harmonic generation (SHG), third-harmonic generation (THG) and the linear, nonlinear, and total optical absorption coefficients (OACs) of a semiparabolic plus semi-inverse squared quantum well (QW) are theoretically investigated. The results show that hydrostatic pressure and temperature have significant effects on the optical properties of semiparabolic plus semi-inverse squared QWs, and that the energy levels and magnitudes of the resonant peaks of OR, SHG, THG, and the total OACs vary according to the shape of the limiting potential, the hydrostatic pressure, and the temperature. It is easily seen that the peak positions of the resonant peaks of OR, SHG, THG, and the total OACs in the semiparabolic plus semi-inverse squared QW show a red shift with increasing hydrostatic pressure, but a blue shift with increasing temperature. Therefore, the magnitude and position of the resonant peaks of OR, SHG, THG, and the total OACs can be adjusted by changing the hydrostatic pressure and the temperature, which promise a new degree of freedom in the tunability of various electro-optical devices.

“…The nonlinear second-harmonic generation and optical rectification in semi-parabolic and semi-inverse squared QWs were investigated by H Hassanabadi et al [12]. Besides, Z H Zhang and co-workers investigated the nonlinear optical properties in several different QWs, such as Morse QWs, Modified-Pöschl-Teller QWs, and Gaussian QWs [13][14][15]. All of the above work indicates that the nonlinear optical properties are sensitively dependent on the shape, structural parameters of QW, and external fields.…”

The third harmonic generation (THG), linear and nonlinear optical absorption coefficients (OACs), and refractive index changes (RICs) are investigated in a Woods-Saxon quantum well (QW) modulated by the hydrostatic pressure and applied electric field. The effect of non-uniform aluminum doping(position-dependent effective mass (PDEM)) on the mass of the system is discussed, and further to explore the influence of PDEM on the nonlinear THG, OACs, and RICs of the Woods-Saxon QW. These nonlinear optical properties above are obtained using the compact-density matrix formalism. The electron states in a Woods-Saxon QW under the constant effective mass(CEM) and PDEM are calculated by solving Schrödinger equation via the finite difference technique. The contributions from competing effects of the hydrostatic pressure and applied electric field to the nonlinear optical properties with CEM and PDEM are reported, as well as the comparison with each other. The observations reveal that the regulation of external fields and the influence of PDEM play an important role in the photoelectric properties of QW.
