Abstract
It has been experimentally observed that moth-eye antireflective microstructures at the end of fibers have an increased laser damage threshold relative to thin-film antireflective coatings. In this work, we computationally study the irradiance enhancement in moth-eye antireflective microstructures in order to explain the increased damage threshold. We show that the irradiance enhancement occurs mostly on the air side of the interfaces and is minimal in the material. We give a physical explanation for this behavior.
