Photonic crystal fibers present a wavelength-scale periodic microstructure running along
their length. Their core and two-dimensional photonic crystal might be based on varied …

The research on perovskite light‐emitting diodes (PeLEDs) has experienced an exponential
growth in the past six years. The highest external quantum efficiencies (EQEs) have …

The “photonic lantern,” an optical fibre device that has emerged from the field of
astrophotonics, allows for a single-mode photonic function to take place within a multimode …

We report the fabrication of what are believed to be the first microstructured optical fibers
with uniformly oriented elliptical holes. A high degree of hole ellipticity is achieved with a …

This chapter outlines three methods for cutting mPOFs as well as giving details of
techniques that have been used to characterise mPOFs through accurate imaging of their …

The dispersion and loss in microstructured fibers are studied using a full-vectorial compact-
2D finite-difference method in frequency-domain. This method solves a standard eigen …

A methodology is presented suitable for the fabrication of a wide range of microstructured
polymer optical fibres (mPOFs), a recent development where light guidance is achieved …

The fabrication, materials, properties and applications of microstructured polymer optical
fibers are reviewed. Microstructured polymer optical fibers formed the basis of extensive …

Early work suggested that very large refractive index contrasts would be needed to create
photonic bandgaps in two or three dimensionally periodic photonic crystals. It was then …

Hollow-core microstructured polymer optical fibres with a kagome lattice cladding are
reported. These fibres do not have photonic bandgaps, instead, leakage from the core is …
