Optical field data compression by opto-digital means
(Institute of Physics Publishing, 2016-12)
Compression of optical field data is of interest due to the many applications where this kind of information processing is necessary. In particular, holographic recording has significant requirements in a high volume of ...
Optical approach for the efficient data volume handling in experimentally encrypted data
(Institute of Physics Publishing, 2016-06)
Experimental optical procedures generate a tremendous amount of data, which must be then processed for any practical application. We present a new optical approach in terms of the data volume for the efficient handling of ...
Single-random phase encoding architecture using a focus tunable lens
(Institute of Physics Publishing, 2016-01)
We propose a new nonlinear optical architecture based on a focus tunable lens and an iterative phase retrieval algorithm. It constitutes a compact encryption system that uses a single-random phase key to simultaneously ...
Antimony glasses with large nonlinear refractive indices, small two-photon absorption coefficients and ultrafast response at telecom wavelengths
Nonlinear (NL) optical properties of antimony oxide based glasses (AG) were characterized for excitation wavelengths from 800 to 1600 m. The NL refractive indices, n2, and the two-photon absorption (TPA) coefficient, β, ...
HIGH EYE-QUALITY IMPROVEMENT BY A SINGLE-SOA REGENERATIVE WAVELENGTH CONVERTER
(John Wiley & Sons IncHobokenEUA, 2010)
Customized data container for improved performance in optical cryptosystems
(IOP Publishing, 2016-12)
Coherent optical encryption procedures introduce speckle noise to the output, limiting many practical applications. Until now the only method available to avoid this noise is to codify the information to be processed into ...
Semiconductor optical amplifier cavity length impact over data erasing/rewriting
Sensorless synchronization method for thin-film direct optical broadband monitoring system
(IOP PUBLISHING LTD, 2011)
Optical monitoring systems are necessary to manufacture multilayer thin-film optical filters with low tolerance on spectrum specification. Furthermore, to have better accuracy on the measurement of film thickness, direct ...
