摘要：

In optoelectronic devices, optical signal transmission gets more affected due to the use of materials and their properties. Here, prepared magnesium oxide (MgO) thin films were studied for optical waveguide application by measuring their optical signal transmission loss (OSTL). Novel vapor chopping technique (VCT) was used to prepare vapor chopped (VC) MgO thin films and properties of those films were compared with as deposited or non-chopped (NC) films. Various oxidation temperatures (573, 623 and 673 K) and thin film thickness variation effect on the OSTL were studied. The VC MgO thin film waveguide showed a smaller transmission loss as compared to the NC MgO thin film waveguides. An AFM study showed that, surface roughness of VC thin films was lower than the NC MgO thin films and it increases with increase in oxidation temperatures. (C) 2019 Elsevier Ltd.
