Cross-sectional transformers for the signal-enhancement of intensity-based evanescent field sensors
A cross-sectional transformer (CST) that allows efficient interconnection between a conventional multimode optical fibre and a broad shallow waveguide, designed for strong interaction of guided modes with sensing materials in the evanescent field, is described. A ray approach is used to determine a...
