Pursuing innovative non-rare earth amplified fibered DFB lasers: Ultra-long fiber Bragg gratings non-linear induced temperature control

Recent years have seen significant leaps towards perfecting the fabrication of ultra-long fiber Bragg gratings (FBGs) for application in non-linear optics, including fibered DFB lasers. Previous work from the laboratory was able to successfully identify and mitigate some of the intrinsic defects causing non-uniformity in multiple type of fibers leading to their compensation attaining high quality reproducible ultra-long FBGs. However, implementation with such novelty components lead to poor results for the DFB fibre laser applications, and further investigation demonstrated temperature gradients along the grating degraded its expected efficiency. This research follows in its footsteps, with the objective of further investigating possible solutions to approach the predicted performance of the DFB laser. Transfer matrix methods using Matlab computation are expected to be a core section of the research. Introducing Kerr non-linearity will allow the simulation of temperature degradation effects. Validation of numerical results will then be experimentally assessed in our laboratories and/or at the partner location.
