Paper Abstract

The paper reviews the area of tapered optical fibers which have significant potential as evanescent field sensing devices. They minimize some of the problems associated with any such device and can be much more sensitive to changes in fluorescence and absorption characteristics. This paper firstly discusses two evanescent field devices which are currently used and then describes the prototype tapered optical fiber device which has been fabricated to demonstrate the principal of operation. Results are presented using the dye Rhodamine 6G as the 'sensing' chemical. Problems associated with the device are considered. Two alternative tapered fiber arrangements are also presented.
