Amplitude-flattened frequency combs in the moving photonic crystals
Hang Qu, Maksim Skorobogatiy
In this paper, we explore the spectral properties of the moving hollow-core photonic crystal waveguides (PCWs). We find that frequency combs could be generated in the hollow cores…

Micro-displacement sensors based on plastic photonic bandgap Bragg fibers
H. Qu, T. Brastaviceanu, F. Bergeron +2
We demonstrate an amplitude-based micro-displacement sensor that uses a plastic photonic bandgap Bragg fiber with one end coated with a silver layer. The reflection intensity of th…
