Abstract
Photonic Crystal Fibres (PCFs) are well known for allowing the implementation of specific waveguiding features that cannot be achieved with conventional optical fibres. This results from the design flexibility of the holey structure in the PCF cladding and/or core regions. Today PCFs have found applications for example in supercontinuum generation, optical sensing and fibre lasers. They are now also being combined with fibre Bragg gratings, more specifically in the fields of optical fibre sensing and all-fibre laser applications. In this contribution we discuss how we applied micro-optical design methods based on commercially available software such as MODE Solutions and FDTD Solutions from Lumerical Solutions, Inc. and COMSOL Multiphysics® combined with MATLAB® scripting and additional optimization methods to develop microstructured fibres for three different purposes, i.e. PCF structures that facilitate Bragg grating inscription, PCF structures that enable temperature insensitive pressure measurements and bendable PCFs with a very large mode area for high power short pulse fibre lasers. For the three cases we describe the fibre design methods and property simulations as well as the tolerance studies that take into account manufacturing imperfections as well as possible variations in material parameters.
