Abstract
Waveguide sensors are formed on a chip package which contains at least one source and at least one detector. Simple waveguide elements are mounted on the chip. Waveguide defining elements can also be formed integrally with the chip package so that simple waveguide bodies can be inserted or removed. Various geometries of source, reference detector, and sensing detector can be produced. A liquid waveguide sensor is formed by filling a waveguide channel with a liquid reagent.
