Impedance self-matching ultra-narrow linewidth fiber resonator by use of a tunable π-phase-shifted FBG

Abstract In this paper, we present a novel ultra-narrow linewidth fiber resonator formed by a tunable polarization maintaining (PM) π-phase-shifted fiber Bragg grating and a PM uniform fiber Bragg grating with a certain length of PM single mode fiber patch cable between them. Theoretical prediction...
