Fabrication of Polymer Optical Fiber as Intrinsic Optical Sensor Using Etching Technique

Fabrication of fiber optic as fiber intrinsic sensor are investigated using Polymer optical fiber (POF) with two variety of etching technique, namely chemical etching and mechanical etching. Chemical etching is prepared by using acetone as etchant solvent, and mechanical etching technique is prepared mechanically by using sand paper and aluminum oxide polishing film. The propagation loss occurred during the chemical etching process and mechanical measured using power meter and photo diode and resulting the acquisition data that is plotted in graph as finally, the etched fiber is used as intrinsic within chemical sensor based on evanescent field absorption. The etching experiment is prepared as initial step to determine the good performance of fabricated sensor in term of producing the good performance of intrinsic fiber sensor.
