In this paper, the phase response of fiber Fabry-Pérot cavity-based fiber optic microphones (FFPC-FOMs) is discussed through an analysis of the results of simulation and experiments. The phase difference of FFPC-FOMs mainly originates from two aspec

The paper deals with the problem of finite-time stabilization for stochastic systems with time-varying delay by defining a new criterion for finite-time stability. Firstly, by use of more appropriate Lyapunov-Krasovskii functional (LKF), the difficul

Many optical properties can be obtained from those propagation modes of optical micro/nano fiber, such as single-mode or hybrid-mode operation, power density distribution, strong confinement, large evanescent field and transmission loss. Here, the TE
