Optical Properties of Gallium Arsenide Cylindrical Quantum Wire, With Applied Magnetic Field.

Abstract

In this study we describe the third harmonic generation of GaAs cylindrical quantum wire with applied magnetic field. The ground and exited state energy eigenvalue of the system are calculated by solving the schrodinger equation. For study the nonlinear optical properties of cylindrical quantum wire, the density matrix formalism is employed, Using this formalism, the third order nonlinear absorption coefficient and refractive index are solved analytically. The graphical analysis is made to interpret the result. The finding show that as the magnitude of static magnetic field increases the magnitude of the third order non linear absorption coefficient and refractive index also increases. Moreover, the maxima of the non linear absorption coefficient and refractive index shifts to wards higher energy (frequency) as the magnitude of static magnetic field increases. This important properties are useful for designing different optoelectronic device.
