Chemo-optical microsensing systems, whether based on fiber optics or integrated optics, show promising prospects. The physical principles underlying chemo-optical waveguide sensors are discussed with the accent on linear evanescent field sensors. The role of the chemo-optical transduction layer is emphasized. Restriction of the freedom of design by technological uncertainties is briefly dealt with. The structure of a complete micro-sensing system is discussed and illustrated by presenting various design of chemo-optical sensors based on surface plasmon resonance.
