Nonlinear wavelength conversion in photonic crystal fibers with three zero dispersion points
, 2010 In this theoretical study, we show that a simple endlessly single-mode photonic crystal fiber can be designed to yield, not just two, but three zero-dispersion wavelengths.

Exact and positive controllability of boundary control systems
Networks & Heterogeneous Media, 2017 Using the semigroup approach to abstract boundary control problems we characterize the space of all exactly reachable states. Moreover, we study the situation when the controls of the system are required to be positive. The abstract results are applied to flows in networks with static as well as dynamic boundary conditions.

Complex order control for improved loop-shaping in precision positioning
, 2019 This paper presents a complex order filter developed and subsequently integrated into a PID-based controller design. The nonlinear filter is designed with reset elements to have describing function based frequency response similar to that of a linear ...
