As optical networks have evolved from point-to-point systems to ring or mesh networks, the
optical devices that are needed to construct optical nodes have become more important and …

Optical communication apparatus for simultaneously and recon? gurably establishing
optical communication chan nels, comprises at least one light source and a plurality of …

Research on space-division multiplexing (SDM) came to prominence in early 2010 being
primarily proposed as a means of multiplying the information-carrying capacity of optical …

Using ultrafast laser inscription, we report the fabrication of a prototype three-dimensional
121-waveguide fan-out device capable of reformatting the output of a 120-core multicore …

Space-division multiplexing based on few-mode multi-core fiber (FM-MCF) technology is
expected to break the Shannon limit of a single-mode fiber. However, an FM-MCF is …

We describe the principle, design, and prototyping of a free-space-optics-based core
selective switch (CSS) for spatial channel (SCh) networks (SCNs) in the age of space …

The strengths and limitations of the photonic technology are reviewed, beginning with the
temporal bandwidth limitations of photonic devices and then focusing on spatial bandwidth …

In-fiber devices enable a vast array of critical photonic functions ranging from signal
conditioning (amplification, dispersion control) to network management (add/drop …

The continuing trend of exponential growth in data communications and processing are
driving the need for large-scale heterogeneous integration. Similar to the trend we have …

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 …
