An All-Optical Binary Pattern Recognition System Applied in Photonic Firewall based on VPI Simulation

2019 24th OptoElectronics and Communications Conference (OECC) and 2019 International Conference on Photonics in Switching and Computing (PSC), 2019
An all-optical binary pattern recognition system based on XOR is simulated by VPI for the first time. The simulation results show the system can recognize and locate target in the data at 10 Gb/s and 40Gb/s.

Optical response of high-level bandgap in one-dimensional photonic crystal applying in-plane integration

Optical Engineering, 2007
A new broadband filter, based on the high level bandgap in 1-D photonic crystals (PCs) of the form Si|air|Si|air|Si|air|Si|air|Si|air|Si is designed by the plane wave expansion method (PWEM) and the transfer matrix method (TMM) and fabricated by lithography.

Analysis of optical locking applied for rephasing halt in photon echoes

Journal of the Optical Society of America B, 2011
Optical locking applied to rephased atoms in photon echoes is analyzed for on-demand photon storage time extension, where the storage time extension is confined by the inverse of spin inhomogeneous broadening. Both optical locking and photon storage mechanisms in atomic frequency comb echoes are discussed and compared with those in two-pulse photon ...

Multi-dimensional time-correlated single photon counting applied to diffuse optical tomography

SPIE Proceedings, 2005
We present a multi-dimensional TCSPC technique that combines multi-detector and multiplexing capability, and records fast and virtually unlimited sequences of time-of-flight distributions. The system consists of four fully parallel TCSPC channels. Each channel records simultaneously in up to eight detection channels.

Photonic data rate reduction applied to ultrafast processing for high speed optical links

2015 6th International Conference on Computers and Devices for Communication (CODEC), 2015
In this paper, we apply photonic data rate reduction based on SOA-loop memories to Deep Packet Inspection (DPI) without the need for high speed opto-electronic conversions. The architecture presented makes use of fast optical subsystems based on Semiconductor Optical Amplifiers, and aided by low cost slow rate electronics; the desired header fields are

Fiber-optical Photon Density Wave spectroscopy applied to highly concentrated biotechnical processes

Imaging and Applied Optics 2016, 2016
Photon Density Wave (PDW) spectroscopy is a novel approach for monitoring biotechnical processes, by independently quantifying the absorption and reduced scattering coefficient of the biomaterial. Enzymatic milk coagulation, beer mashing and blood deoxygenation are discussed.

Phase-sensitive optical low-coherence reflectometry technique applied to the characterization of photonic crystal fiber properties

Optics Letters, 2005
Localized measurements of group-velocity dispersion and birefringence of photonic crystal fibers are achieved with a phase-sensitive optical low-coherence reflectometry technique. This technique is efficient for fiber samples no longer than 1 m. Theoretical simulations are in good agreement with experimental results.
