Detailed analysis of near and far field intensity distribution in Gallium nitride superlattice structure has been carried out through the general solutions of wave equation and effective index has been deduced using effective index method to explore optical confinement and optical field. To obtain the better optical confinement in Superlattice structure, the physical and structural parameters like thickness of wells and barriers, wavelength, Aluminum mole composition of barrier and temperature have been optimized. The analysis of far field intensity is carried out as a function of wavelength and aluminum mole fraction in the temperature range of 300 to 370 K. It is deduced from our analysis that the Aluminum mole fraction in the barrier region strongly influences near field, far field divergence and the optical confinement.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
