30 Years of Fiber Bragg Grating Sensor Technology
ADK Consulting and Insight Photonic Solutions, Inc., USA
Abstract: The first publication on the sensing potential for side-written Bragg gratings in optical fiber appeared as a patent PCT publication by the Meltz et al. group from UTC in 1986. In the 30 years that have followed, we have seen an extraordinary series of developments in fiber Bragg grating (FBG) sensor technology, taking it from early conceptual laboratory demonstrations to powerful commercial distributed sensing platforms, with many companies now developing and marketing FBG systems and ‘interrogator’ units. This paper will review this history, highlight some of the key developments in the sensing capabilities developed and touch on some truly novel applications of the technology. The paper will also review more recent applications based on the use of extremely weak draw-tower written grating arrays that exploit the unique properties of Bragg gratings in ways to enable creative & differentiated sensing capabilities.

Nonlinear world of commercial photonic systems

Many nonlinear photonic technologies are already weaved into the operation of commercial systems. Nonlinearity is an essential component in the design of numerous photonic devices, but it is often shunned by engineers in view of its practical intractability and greatly increased difficulty of comprehension of system behavior. The understanding and mastering of nonlinear effects can translate into improving performance of the existing devices and enabling a new generation of engineering concepts. Our recent work on nonlinear science of fibre lasers and optical communications systems will be reviewed.
