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 …

Integrated photonics is attracting considerable attention and has found many applications in
both classical and quantum optics, fulfilling the requirements for the ever-growing complexity …

Technologies for efficient generation and fast scanning of narrow free-space laser beams
find major applications in three-dimensional (3D) imaging and mapping, like Lidar for …

Quantum walks, in virtue of the coherent superposition and quantum interference, have
exponential superiority over their classical counterpart in applications of quantum searching …

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 …

The extremely high peak intensity associated with ultrashort pulse width of femtosecond
laser allows us to induce nonlinear interaction such as multiphoton absorption and tunneling …

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 …

We show how multiple optimal orthogonal channels for communicating or interconnecting
with waves between two objects can be aligned and optimized automatically using …

Photonic technologies offer numerous functionalities that can be used to realize
astrophotonic instruments. The most spectacular example to date is the ESO Gravity …
