Silicon photonics is an enabling technology that provides integrated photonic devices and
systems with low-cost mass manufacturing capability. It has attracted increasing attention in …

In order to overcome the capacity limitations of current lightwave systems based on the
single-mode optical fiber, massively parallel transmission in the spatial domain [space …

Exploiting a particular wave property for a particular application necessitates components
capable of discriminating in the basis of that property. While spectral or polarisation …

Space-division multiplexing (SDM) uses multiplicity of space channels to increase capacity
for optical communication. It is applicable for optical communication in both free space and …

Single-mode fibres with low loss and a large transmission bandwidth are a key enabler for
long-haul high-speed optical communication and form the backbone of our information …

Many advanced optical functions, including spatial mode converters, linear optics quantum
computing gates, and arbitrary linear optical processors for communications and other …

Mode division multiplexing (MDM)–using a multimode optical fiber's N spatial modes as data
channels to transmit N independent data streams–has received interest as it can potentially …

We designed and built a new type of spatial mode multiplexer, based on Multi-Plane Light
Conversion (MPLC), with very low intrinsic loss and high mode selectivity. In this first …

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 …

As traffic volumes carried by optical networks continue to grow by tens of percent year over
year, we are rapidly approaching the capacity limit of the conventional communication band …
