We present long period grating (LPG) fabrication and application of LPG as chemical sensor. We fabricated LPG of grating period 610μm in single mode communication grade fiber using point by point method. Here we used 12watt CO2 laser to irradiate the fiber. The behavior of resonance wavelength of LPG was studied by immersing it in nitrate solution of concentration ranging from 10ppm to 50ppm. The...
This paper reports the bend induced optical loss in a buffered single mode fiber has been measured as an oscillatory function of temperature. The experimental observations are explained based on interference between the core-guided modes and whispering gallery modes formed by the reflection at the buffer–air interface. The observed results are consistent with the optothermal properties of the fiber...
