Light with suppressed quantum fluctuations is desirable for a lot of applications. There are several approaches to suppress a noise including Kerr squeezing in optical fibres. Silica fibres are commonly used for this purpose. Here we propose to use h

We report on fabrication of tapered circular depressed-cladding waveguides in Nd:YAG crystal by femtosecond laser direct writing (FsLDW). Based on the fabricated waveguides, for the first time to the best of our knowledge, efficient Q-switched mode-l

We report on the realization, calibration, and test outdoor of a 19-inches rack 3-units sized Quartz Enhanced Photoacoustic Spectroscopy (QEPAS) trace gas sensor designed for real-time carbon monoxide monitoring in ambient air. Since CO acts as a slo

A scheme of optical four-level pulse amplitude modulation (PAM-4) is proposed based on phase-dependent electromagnetic-induced transparency (EIT) in nitrogen-vacancy (NV) centers. For a closed structure, its transmission depends on the relative phase

Electronic properties of Cs2(Ti, Zr, Hf)X6, where X = I, Br, and Cl in vacancy-ordered double perovskite (VODP) structure were studied by using the density functional theory (DFT) calculation with the Heyd–Scuseria–Ernzerhof (HSE) hybrid function

The actuator disc method is an engineering approach to reduce computer resources in Computational Fluid Dynamics (CFD) simulations of helicopter rotors or aeroplane propellers. Implementation of an actuator disc based on rotor circulation distributio

The paper presents a novel multi-pass point-by-point method for high-precision inscription of fiber Bragg gratings with a femtosecond laser radiation. The dynamics of the gratings formation is demonstrated in comparison with the classical method of U

Single-mode waveguide devices are necessary in photonic integrated circuits. Previous studies on the single-mode conditions (SMCs) of the thin film lithium niobate (TFLN) either only focus on wire waveguide, or lack comprehensive discussions on the i

Nowadays, more and more metamaterial absorbers (MMAs) are explored not only in the microwave band but also in terahertz band, but few studies concentrate on metamaterial absorbers which can work in cross-band, that to say, absorb gigahertz (GHz) and
