All-optical spectral shuffling of signals traveling through different optical routes
(2019-07-01)
A recent proposed physical layer encryption technique uses an all-optical setup based on spatial light modulators to split two or more wavelength division multiplexed (WDM) signals in several spectral slices and to shuffle ...
Spectral shuffling with phase encoding and dynamic keys applied to transparent optical network signals
(2020-07-01)
A recently proposed signal encryption technique consists in shuffling the samples of two or more baseband signals, which are then modulated in different optical carriers and transmitted by transparent optical networks. In ...

All-optical Spectral Shuffling Applied to 16-QAM Signals
(Ieee, 2019-01-01)
All-optical spectral shuffling (AOSS) is a recently proposed physical layer encryption technique. In AOSS, multiple input signals are split in several spectral slices. These slices are then shuffled to form multiple encrypted ...

A New DSP-Based Physical Layer Encryption Technique Applied to Passive Optical Networks
(2018-09-26)
Point-to-multipoint architecture poses serious security problems to passive optical networks (PONs). In this paper, we propose the use of a new digital signal processing (DSP)-based technique to improve the confidentiality ...
HIGH EYE-QUALITY IMPROVEMENT BY A SINGLE-SOA REGENERATIVE WAVELENGTH CONVERTER

2D Instantaneous Frequency-based Method for Motion Estimation using Total Variation
(Institute of Electrical and Electronics Engineers, 2014-12)
We present a first approach to a new method to compute the motion estimation in digital videos using the two-dimensional instantaneous frequency information computed using amplitude-modulation frequency-modulation (AM-FM) ...
