DOI: 10.1109/tim.2025.3625330

Abstract: To conduct an in-depth study of the prefracture process of composite coal–rock bodies under varying loading rates and coal content, the axial strain characteristics and electromagnetic radiation (EMR) theory related to the fracture were analyzed.… read more here.

DOI: 10.1364/oe.450091

Abstract: An in-line Mach-Zehnder interferometer based on a multimode-fiber-assisted tapered open-cavity (TOC) is proposed. Light field distributions of the TOC were investigated using beam propagation method with different offsets and diameters of the taper waist. Bias… read more here.

DOI: 10.1364/oe.452783

Abstract: To solve the cross-sensitivity problem in the dual-parameter optical fiber system, a new type of sensor based on cascaded interference structure is proposed without cross-sensitivity. The design consists of a Michelson interferometer and a Sagnac… read more here.
