Optical regeneration using a feedforward semiconductor optical amplifier with chirp-controlled filtering
(John Wiley & Sons IncNew YorkEUA, 2001)
Dynamic multiple-image encryption based on chirp z-transform
(IOP Publishing, 2019-02)
It is demonstrated a dynamic encryption scheme based on chirp − z transform (CZT). The novel design of this setup allows to protect multiple images in a multiplexed format and fully recover them without the influence of ...
Surface solitons in chirped photonic lattices
(2007)
We study surface modes at the edge of a semi-infinite chirped photonic lattice in the framework of an effective discrete nonlinear model. We demonstrate that the lattice chirp can change dramatically the conditions for the ...
Simulations on picosecond non-linear electro-optic switching using an ASE-calibrated semiconductor optical amplifier model
(Elsevier Science BvAmsterdamHolanda, 2004)
Asymmetric multiple-image encryption system based on a chirp z-transform
(Optical Society of America, 2019-07)
An asymmetric multi-image encryption system based on the chirp z-transform (CZT) is demonstrated. The setup is a hybrid architecture that combines a double-random-phase encryption scheme in 4f configuration and a multiplexing ...
