Optical Correlation with Light of Tunable Wavelength
نویسندگان
چکیده
A novel method is described for compensation of size variations in the input pattern of an optical correlator for pattern recognition by appropriate adjustment of the reconstruction wavelength. Simple ring-shaped patterns of variable diameter have been optically cross-correlated. Using a tunable dye laser of narrow bandwidth, the correlator output was analyzed for various combinations of size and wavelength to show the performance of the method.

متن کاملTunable Plasmonic Nanoparticles Based on Prolate Spheroids
Metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. Spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using Mie theory. However a major disadvantage of metallic spherical nanoparticles is ...

We demonstrate a tunable optical tapped delay line that can simultaneously and independently operate on multiple wavelength-division multiplexed (WDM) data signals. The system utilizes the wavelength-dependent speed of light, together with nonlinear wavelength conversion stages. A phase-preserving scheme enables coherent addition of the weighted taps. We reconfigured the system to perform separ...
