Determination Of Volume And Surface Contributions To The Total Attenuation In Zns Waveguides

Abstract

We relate the modal waveguide attenuation of polycrystalline ZnS films to their mode field properties, namely the field amplitudes at the interfaces and the power confinement factor, to show that the total waveguide attenuation is caused by a combination of volume and surface effects. Our results show that the surface losses for the TEO mode, which are approximately 1.5 dB/cm, are independent of the total attenuation, which varies from 6 to 40 dB/cm. This suggests that the losses of the lower-order modes are dominated by volume effects such as scattering from crystallite boundaries and absorption. © 1993 Optical Society of America.
