In this article, the composite π-joint is investigated under bending loads. The “L” preform is the critical component regarding composite π-joint failure. The study is presented in the failure detection of a carbon fiber composite π-joint structure under
Two-dimensional (2D) materials have emerged as attractive mediums for fabricating versatile optoelectronic devices. Recently, few-layer molybdenum disulfide (MoS2), as a shining 2D material, has been discovered to possess both the saturable abs
A multilevel grating coupler based on silicon-on-insulator (SOI) material structure is proposed to realize the coupling between waveguide and waveguide or waveguide and fiber. This coupler is compatible with the current fabrication facilities for compleme
