Abstract:
In this study we have developed the Hamiltonian and trial wave functions for the
triangular quantum well. Then the schroendinger equation is solved analytically and
numerically for determining the ground and excited state energy. This ground and
excited state energy of triangular quantum well are calculated by using variational
methods. The energy eigen value of states increase with an increment of applied field.
By using the compact density matrix formalism and iterative procedure, the change
in linear refractive index and absorptions coefficient is studied. The value of linear
change in refractive index and absorption coefficient carried out for given value of
transition energies and depending on the above calculated energy eigen value. As
the transition energy or frequency increases, the peak of the spectra of the change
in refractive index and change in linear absorption coefficient move toward the high
energy region. Moreover, the magnitude of the absorption coefficient increases with
an increment of transition energy.
