Abstract: In this manuscript we have investigated the fabrication of PEO embedded planar optical waveguide (POW) sensor. To improve the sensing characteristics of POW, it has coated with conducting polymer poly ethylene oxide (PEO). The embedded waveguide prepared with variant thermal ion exchange process with various time duration of 20,40,60,80,100,120 minutes on sodium silicate glass. The properties of modified planar optical waveguide enhance the sensing activity, which can help to study the characteristics of soil by doping of different fertilizers with x wt% (x=1, 2, 3, 4, 5) of varying concentrations. The use of appropriate percentage of fertilizer in different soil yield good healthy crop. The laser technique is used to study the POW for characteristics of soil. The material characterization study done by scanning electron microscopy (SEM) and small angle X-ray diffraction (XRD) revealed the formation of K+ ions layer in surface-near regions of the sample at optimum expose time period of 120 minutes at 380 0C. It gives an advantageous application for unidentified soil character analysis. Copyright © 2017 VBRI Press.
