Synchronization of chaos in microchip lasers and its communication applications

Abstract

We overview some experimental and numerical demonstrations on the synchronization of chaos and its communication applications using Nd:YVO 4 microchip solid-state lasers. Synchronization of chaos is achieved with several coupling configurations. Several encoding and decoding schemes for communication applications are also demonstrated by using the synchronization of chaos in microchip lasers. A new approach to secure communications using chaos based on information theoretic security is introduced. To cite this article: A.

Optical Spectroscopy and Visible Upconversion Studies of YVO4:Er3+ Nanocrystals Synthesized by a Hydrothermal Process

“…Rare-earth-doped luminescence materials have wide applications, including phosphors, display monitors, X-ray imaging, scintillators, lasers, and amplifiers for fiber-optic communications. − The luminescence efficiency of these materials is often limited by the dynamics of the rare-earth (RE) ion, which depends on the interaction between RE ions and the host . Among many RE ions, trivalent erbium ion is well-known as an active dopant for many different inorganic lattices, producing white-light emission by adjusting the ratio of blue, green, and red emissions. , In addition, an Er 3+ ion is particularly suitable for the upconversion of infrared to visible light because of a favorable electronic level scheme with equally spaced, long-lived excited states.…”

Synchronization of microresonator frequency combs in chaotic regime

“…Chaos synchronization has been studied since 1665 [1] when Huygens reported experimental results for the synchronization of two metronomes. Centuries later, there have been numerous contributions that use this principle of chaos synchronization for different applications, including in laser technologies [2], secure communication [3], precision spectroscopy [4], and clock dissemination [5].…”
