slugCalculating Transmittivity of Photonic Multiple Quantum Well for S-Polarized Incidence
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 4
Abstract
Novel bandpass filter is proposed using photonic multiple quantum well structure by computing transmittivity for normal and oblique incidence of s - polarized electromagnetic wave. Ratio of thickness of unit cell and material composition of t he barrier region is varied to compute the modulation in filter bandwidth using transfer matrix technique for optical communication purpose at 155 0 nm. Al x Ga 1 - x N/GaN composition is chosen as unit block of the periodic organization, with Al x Ga 1 - x N layer as the barrier and GaN as well of the 11 - layer structure. Following Adachi’s model, refractive index of Al x Ga 1 - x N is considered as a function of mole fraction and operating wavelength. It is found out that for normal incidence, this structure demonstrate bett er filter characteristics than oblique incidence. Suitable choice of dimension and Al mole fraction along with variation of incident angle makes it efficient band - pass filter at desired frequency region.
