Switchable Analogue of Electromagnetic Induced Absorption and Transmission-Like Filter Responses Using Stimulated Brillouin Scattering
The constructive/destructive quantum interference due to coherent interaction between multi-level atoms generates electromagnetic induced absorption/transparency (EIA/EIT) [1]. EIT has a transparent spectral window in the absorption spectra, and EIA has a narrow absorption window in the transmission spectra. EIA/EIT has been demonstrated in atomic systems [2], [3], and analogue filter responses have also been demonstrated using stimulated Brillouin scattering [4], [5]. In this paper, we present a method to generate switchable EIA/EIT-like RF filters using Brillouin-induced loss tailoring. Flexible filter shaping enables highly versatile responses with tunable bandwidths and central frequencies which can have applications in wireless signal processing and RADARs.
