A polarization-maintained coupled optoelectronic oscillator (COEO) with its performance significantly improved by a short-length unpumped erbium-doped fiber (EDF) is reported and experimentally investigated. A 10 GHz optical pulse train with a supermode s
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
