Ultrafast and energy-efficient all-optical switching with graphene-loaded deep-subwavelength plasmonic waveguides

Nature Photonics, 2019
All-optical switches have attracted attention because they can potentially overcome the speed limitation of electric switches. However, ultrafast, energy-efficient all-optical switches have been challenging to realize owing to the intrinsically small ...

Lightwave Fabrics: At-Scale Optical Circuit Switching for Datacenter and Machine Learning Systems

IEEE/LEOS International Conference on Optical MEMS, 2023
We describe our experience developing what we believe to be the world’s first large-scale production deployments of lightwave fabrics used for both datacenter networking and machine-learning (ML) applications [1],[2],[3],[4].

Optical Hybrid Switching – Combined Optical Burst Switching and Optical Circuit Switching

2004
In this paper, we propose a new optical hybrid switching technique which combined Optical Burst Switching (OBS) and Optical Circuit Switching (OCS) using flow classification. In particular, this switching technique classifies incoming IP traffic flows into short-lived and long-lived flows for Quality of Service (QoS) provisioning according to traffic ...

Anisotropic Nonlinear Optical Properties of a SnSe Flake and a Novel Perspective for the Application of All‐Optical Switching

Advanced Optical Materials, 2019
The deceptively simple tin selenide (SnSe) film has emerged as an appealing 2D material with a narrow bandgap, high charge carrier mobility, and significant thermoelectric figure of merit.

Compact optical crossbar switch

Applied Optics, 1997
A novel compact holographic crossbar architecture based on planar optics is presented. It consists of a pair of identical planar holographic elements, a two-dimensional array (N x N) transmission mask, a one-dimensional array (N) of input light sources, and a one-dimensional array (N) of detectors.

Optical Buffering and Switching for Optical Packet Switching

2006 International Conference on Photonics in Switching, 2006
We describe the design and initial results of an all-optical buffered 40 Gb/s packet switch. Dynamic packet forwarding is illustrated and specific attention is directed to buffering. We assess the challenges in meeting the requirements for optical buffering devices. Slow light and delay line buffering approaches are described and several recent results

Micromotor grating optical switch

Optics Letters, 1995
We describe polysilicon micromotors with diffraction gratings fabricated on the polished surface of the polysilicon rotor for optical switching applications. The motors have rotor diameters of 0.5–2 mm with grating elements having periods of 1.80 and 3.86 μm. These microswitches have rise times of 300 μs and settling times of 500 μs when driven by a 65-

Optical Switching in Chiropticenes

Annals of the New York Academy of Sciences, 2003
Abstract: Chiropticenes™ are a novel class of predesigned chiral molecular switches that are triggered and controlled by a combination of both light and electric field. Chiropticenes contain an optically active (chiral) center and, as a consequence, provide two accessible equal energy bistable states resembling the molecular elements of binary logic ...
