Abstract

Efficient low loss components that are compatible with optical fibers are essential for the successful implementation of many single mode fiber optic sensor systems. In this paper we investigate the use of Langmuir-Blodgett (LB) films as waveguiding overlays evanescently coupled to side polished optical fibers which result in useful in-line wavelength selective elements. We demonstrate the use of two LB film- forming materials: firstly a simple fatty acid is used for a passive channel dropping device and secondly it is shown that hundreds of layers of a more complex electro-optic molecule may be successfully deposited onto fibers prepared using an alternative polishing technique, which does not require extensive surface preparation.
