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.
