TL;DR: In this paper, the authors demonstrate that terahertz (THz) emission can be controlled by the spin structure of noncollinear antiferromagnetic metal Mn3Sn.

TL;DR: In this article, a magnetic-field-tuned photonics device based on magnetic fluid (MF) and a square tapered no-core fiber (NCF) sandwiched between two single-mode fibers (SMFs) is demonstrated experimentally and theoretically.

TL;DR: In this paper, a photonic crystal fiber based on surface plasmon resonance (PCF-SPR) temperature sensor with liquid core is proposed, where glycerin liquid with a high refractive index is filled in the central air hole of the hollow core photonic bandgap (PBG) PCF, which will change to total internal reflection (TIR), which will significantly broaden its transmission bands.

TL;DR: A relative humidity (RH) sensor based on long-period grating (LPG) with different responses is proposed by utilizing agarose gel as the sensitive cladding film, which would find its potential applications in high humidity level, temperature-independent RH sensing and multiparameter sensing based on wavelength/power hybrid demodulation.

TL;DR: A continuous-wave mid-infrared intra-cavity singly resonant optical parametric oscillator (ICSRO) which is the first example of ICSRO that utilize in-band pumped Nd-doped vanadate laser as pump source is reported.
