> FIBER SENSORS
A KEEN SENSE.
Modern waveguides are not only used in telecommunications for data transfer, but also progressively open up areas of application in the field of sensor and lighting technology. The use of laser technology for the functionalization of fiber ends and the optimization of the construction and assembly of fibers results in manifold scopes of design. Thus, fibers can purposely be structured on lateral surfaces by means of a laser beam in order to use the decoupled light for lighting or to couple signals into the fiber.
The know-how of the construction and assembly of fiber-optical systems is applied for example to realize fiber-based sensors for the analysis of the composition of liquids by taking advantage of the Raman effect. The laser is particularly used for joining of glas-glas connections or for creation of minimal drillings in hollow core fibers. Special micro-structured hollow core fibers are used which are developed and produced by the Canadian partner INO. The advantage of these novel fiber architectures lies in expanding the diversity and reducing the quantity of substances to be analyzed. Due to the large interaction length, which is achieved through the hollow core fibers, even the smallest traces of substances can be detected.
