  Design and Fabrication of Tapered Optical Fiber Related Devices

  By Keyur Raju Ninawe, Sahil Narendra Narlawar, Onkar Shivaji Jadhav, Ganesh N Gaikwad

  Abstract: By joining conical single-mode fibers, a Mach-Zehnder interferometer with a refractive index (RI) sensor was produced. Sensors were made directly from conical SMFs using a Vytran engine. Compared to the single-taper sensor, the dual-taper sensor turned out to be more efficient. With a 10mm gap between the two taper sites in the dual-taper sensor arrangement, the RI fluctuation was quite noticeable. The principles underlying the design and fabrication of tapered …

  An Investigation on Influence of Gamma Irradiation and Doping on Chemical Structure and Optical Properties of Conducting Polypyrrole

  By N Venkateswara Rao, B Sanjeeva rao, A Raju

  Abstract: In this study the authors report on effect of gamma irradiation and doping (bromine, iodine and sulfate ion) on chemical structure and optical, electronic properties of poly pyrrole. Optical absorption spectrum of PPY shown absorption bands centered around 36.2.5nm (peak 1), 450 nm (peak2) and 525 nm (peak 3) positions Gamma irradiation resulted in broaden of peak A together with a band shift of 45- 525 nm and disappearance peaks …
