The growing maturity of integrated photonic technology makes it possible to build
increasingly large and complex photonic circuits on the surface of a chip. Today, most of …

Data rates in optical fiber networks have increased exponentially over the past decades and
core-networks are expected to operate in the peta-bit-per-second regime by 2030. As …

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

An optical vortex having an isolated point singularity is associated with the spatial structure
of light waves. A polarization vortex (vector beam) with a polarization singularity has …

Space-division multiplexing (SDM) is an attractive technique for dramatically enhancing the
transmission capacity in a single optical fiber. Recently, ultradense SDM transmission …

A few decades ago, quantum optics stood out as a new domain of physics by exhibiting
states of light with no classical equivalent. The first investigations concerned single photons …

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 …

In order to overcome the capacity limitations of current lightwave systems based on the
