We report on the generation of multiwavelength Q-switched pulses from a Ytterbium-doped fiber laser (YDFL) cavity by employing a nickel nanoparticle (Ni-NPs) thin film as an optical modulator. Owing to the high nonlinearity of Ni-NPs and the distinguished saturable absorption property, stable single-, dual-, triple-, or quadruple-line, Q-switched generation with a 0.7 nm channel spacing have been achieved

Microwave photonics (MWPs) is an emerging interdisciplinary field, where photonics technologies are adopted to facilitate the generation, transmission, detection, and processing of signals at radio-wave, microwave, and millimeter-wave frequencies. Recently, the integrated photonic technology has demonstrated its capability to miniaturize photonic circuits on a single chip, which paves the way for next-generation

The existing fiber-based optical access technologies in the Republic of Kosovo are reviewed in this article. A historical background to the wireline technologies is provided with the focus on fiber-based technologies. This is combined with a description of the current deployments and the future prospects for fiber-based optical access technologies. In addition, the market share in the Kosovan telecommunications

In this paper, we propose and numerically simulate a microwave photonic phase-tunable frequency converter (MPPTFC) without optically filtering to realize both frequency up- and down-conversion and a full 360° phase-shift for the microwave signal based on an integrated dual-polarization dual-parallel Mach–Zehnder modulator (DP-DPMZM). In the proposed scheme, both microwave RF signal and frequency-tunable
