Frequency Agnostic RF-Photonic Limiter with GeAsSe Tapered Fiber Brillouin Laser

Abstract

A RF-photonic limiter capable of frequency agnostic suppression of strong RF interferers was demonstrated. By using stimulated Brillouin scattering in a Brillouin laser comprising polarization maintaining GeAsSe micro-structured optical fiber tapers, limiting of multiple simultaneous in-band interferers can be achieved with minimal degradation of wideband signals.
