Modelling, Sensor, Environment
To be useful in real-life applications in the industrial or medical environment, a sensor system must be able to communicate, adjust its operation and make a decision. A tapered waveguide is formed that can be sensitised to environmental conditions by using a measurand for the cladding in order to modify the guidance properties of the waveguide. An integrated sensor system is presented where by such a waveguide is chemically etched by exposure of an optical material to a solvent, in order to define the waveguide parameters. To simulate this process, the waveguide is replaced by an optical fibre that is tapered by a solvent in an automated system.
