Here, an experimental verification is done to evaluate the performance variations of the U-bent plasmonic silver coated sensor surfaces with different coating orientations inside the vacuum coating chamber. The performances of uncoated, partially coated as well as fully coated optical fiber U-bent surfaces are analyzed. The results show that the coating configuration of the U-bent surfaces can affect the sensing property. A fully silver coated sensor region outperforms the other two types of sensor surfaces with better sensing capability. Hits: 1016 Download times: 0 View Full Text    Download reader
