Photonic fibers and waveguides

Research output: Chapter in Book/Report/Conference proceedingChapter


Over the last few decades, the use of photonic fibers and waveguides in astronomical instrumentation has grown substantially. This paper provides a summary of the driving motivations for this growth. We also provide a description of the key devices and concepts that include photonic lanterns, fiber Bragg gratings (FBGs), waveguide Bragg gratings, hexabundles, mode scrambling fibers, integrated beam combiners and nullers, ring resonators, and integrated spectrographs. In the years ahead, as emerging photonic fields grow in maturity, we expect to see a regular sequence of such new techniques transitioning through lab demonstration, on-telescope demonstration, and onto new science results.
