Processing of materials by ultrashort laser pulses has evolved significantly over the last
decade and is starting to reveal its scientific, technological and industrial potential. In …

Photonic lanterns are made by adiabatically merging several single-mode cores into one
multimode core. They provide low-loss interfaces between single-mode and multimode …

Four-mode multiplexing and manipulation technologies are reviewed in the context of space-
division multiplexing (SDM) optical communication systems. These are multiplane light …

Since the discovery that tightly focused femtosecond laser pulses can induce a highly
localised and permanent refractive index modification in a large number of transparent …

Photonic technologies offer numerous advantages for astronomical instruments such as
spectrographs and interferometers owing to their small footprints and diverse range of …

Multimode optical fibers have been primarily (and almost solely) used as “light pipes” in
short distance telecommunications and in remote and astronomical spectroscopy. The …

We demonstrate fabrication of single-mode circular optofluidic waveguides in fused silica
glass substrates using femtosecond (fs) laser assisted chemical etching based on slit beam …

Astrophotonics is the application of photonic technologies to channel, manipulate, and
disperse light from one or more telescopes to achieve scientific objectives in astronomy in …

Coupling of light into multi-core fibers (MCF) for spatially resolved spectroscopy is of great
importance to astronomical instrumentation. To achieve high coupling efficiencies along with …

The majority of optical fiber technology developments in the applied sciences have arisen
from developments in telecommunications. However, the photonic lantern is one of several …
