Open waveguides are widely used in modern photonic devices, such as microstructured fiber filters and sensors. Their absorption and transmission spectra are the most important properties in determining the overall performance of the photonic devices. The
Aiming at the defects of passive optical network (PON) monitoring based on optical time domain reflectometry (OTDR) technology, we research the non-OTDR monitoring technology. The coding scheme based on periodic encoder monitoring is discussed, and its li
Based on the principle of virtual equivalent gain, the evolution of self-similar pulses in a normal dispersion-decreasing fiber is investigated. The occurrence of wave breaking during the process under highly nonlinear conditions and the effect of its rev
