Optical signal processing has been playing a crucial part as powerful engine for various
information systems in the practical applications. In particular, achieving large-scale …

In this paper, we present a new concept of electro-optical plasmonic Set-Reset flip-flops at
mid-infrared frequencies. We use the 3D finite-difference time-domain (FDTD) method to …

A compact silicon photonic wavelength-selective switch (WSS) based on an array of
elliptical microrings with adiabatically varied radii and widths is proposed and demonstrated …

In this work, we describe a procedure for synthesizing racetrack resonators with large quality
factors and apply it to realize a multi-channel wavelength-selective switch (WSS) on a silicon …

An integrated flexible-grid 1× 2 wavelength-selective switch based on reconfigurable add–
drop silicon microring resonators using strip waveguides is designed and experimentally …

A polarization-insensitive flexible-grid wavelength-selective switch using silicon-based
double-series coupled microring resonators and polarization splitter-rotators are presented …

In this article, a design of integrated flexible-grid mode-and wavelength-selective switch
consisting of silicon-based symmetric Y-junctions and double-series coupled microring …

Mixed-line-rate wavelength division multiplexing (WDM) networks with discrete channel
spacing generalize the fixed grid WDM networks and can support mixed-electronic-optical …

A non-volatile flexible-grid wavelength-selective switch (NVFGWSS) based on
subwavelength-grating-Ge2Sb2Te5 (GST)-assisted silicon microring resonators (MRRs) is …

Driven by future (beyond 5G and 6G) services and applications, optical networks are
required to support an ever increasing and more dynamic data traffic in a flexible and …
