The bus voltage of the ship DC microgrid is sensitive to the change of loads, which has an influence on the power supply quality. This paper introduces a hybrid energy storage system (HESS) that is composed of a battery set and a supercapacitor set,

We study the point-by-point inscription of sapphire parallel fiber Bragg gratings (sapphire pFBGs) in a fully multimode system. A parallel FBG is shown to be critical in enabling detectable and reliable high-order grating signals. The impacts of moda

Although 3D positional tracking of single nanoparticles in suspension is now an established technique, the small size of the particles compared to the wavelength of light has meant it is still challenging to optically characterize individual diffusin

This paper presents parallel FBGs in sapphire fiber to significantly boost the signal intensity of high order FBGs. Cascaded parallel FBGs are fabricated and achieve multi-point high temperature sensing.

An in-fiber twist sensor based on point-by-point-inscribed off-centered FBG in a two-mode fiber is demonstrated. Twist sensing over a range of -180° to 180° is achieved with a reflection-based system.
