All-optical switch with two periodically curved nonlinear waveguides [PDF]
Optics Letters, 35(3) 321-323(2010), 2008 We propose a type of all-optical switch which consists of two periodically curved nonlinear optical waveguides placed in parallel. Compared to the all-optical switch based on the traditional nonlinear directional coupler with straight waveguides, this all-optical switch has much lower switching threshold power and sharper switching width.

SOA-Based Label Extractor for Optical Burst Switching Application
IEEE Photonics Technology Letters, 2014 This letter presents experimental results of a label extractor for labeled-optical burst switching (OBS) applications. The extractor uses a semiconductor optical amplifier in the amplifying detection mode to extract the label part of a burst with ...

Coded Packet Transport for Optical Packet/Burst Switched Networks [PDF]
Published in 2015 IEEE Global Communications Conference (GLOBECOM), 2016 This paper presents the Coded Packet Transport (CPT) scheme, a novel transport mechanism for Optical Packet/Burst Switched (OPS/OBS) networks. The CPT scheme exploits the combined benefits of source coding by erasure codes and path diversity to provide efficient means for recovering from packet loss due to contentions and path failures, and to provide ...

Super pulses of orbital angular momentum in fractional-order spiroid vortex-beams [PDF]
, 2017 We consider optical properties of Hypergeometric-Gaussian beam compositions with spiral-like intensity and phase distributions that were called the spiroid beams. Their orbital angular momentum as a function of a fractional-order topological charge has a chain of supper-pulses (bursts and dips).The form of the supper-pulses can be controlled by the ...
