We propose and experimentally demonstrate compact on-chip 1× 2 wavelength selective
switches (WSSs) based on silicon microring resonators (MRRs) with nested pairs of …

Wavelength selective switches (WSSs) that are integrated in reconfigurable optical add-drop
multiplexers (ROADMs) induce penalties on the optical signal due to tight optical filtering …

At the lowest layer of today's communication networks is an optical line system (OLS), a
physical network of equipment, which carries high-frequency analog light signals over …

In all-optical WDM networks, feasibility of a lightpath are determined by physical layer
impairment accumulation. Physical layer impairment-aware routing and wavelength …

Next-generation optical networks require high-degree, high-capacity reconfigurable optical
add-drop multiplexer (ROADM) nodes and intelligent network planning schemes. We …

We describe the impact of passband shape and random center frequency variations on the
bandwidth narrowing caused by successive filtering in concatenated wavelength-selective …

Mode blocking may be required in mode-division multiplexing (MDM) systems. We
demonstrate a silicon mode blocking filter using a subwavelength grating-based contra …

Reconfigurable Optical Add/Drop Multiplexers (ROADM) are the optical switching equipment
of transparent optical networks. Directionless ROADMs permit the network carriers to …

Due to crosstalk-induced interactions among different connections, malicious high-power
jamming signals can potentially spread widely in a transparent optical network. Moreover …

The main goal of this paper is to explore the radiative cooling and solar heating potential of
several materials for the built environment, based on their spectrally-selective properties. A …
