Experimental distinction of Autler-Townes splitting from electromagnetically induced transparency using coupled mechanical oscillators system

Abstract: Here we experimentally demonstrated the electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS) effects in mechanical coupled pendulums. The analogue of EIT and ATS has been studied in mechanical systems and the intrinsic physics between these two phenomena are also been discussed. Exploiting the Akaike Information Criterion, we discern the ATS effect from EIT effect in our experimental results.

“…Hence, both PITlike peaks are mainly caused by ATS effect rather than EIT phenomenon. As explained in [32][33][34], these results indicate that the lower vertical GNR (bright-mode) is strongly coupled to the upper horizontal ribbon (dark-mode). In other words, the two GNRs lie in the strong coupling regime in which the mode splitting is mainly attributed to ATS.…”

“…To figure out if the observed PIT-like resonances in the transmission spectrum of the system are originated by EIT or Autler-Townes splitting (ATS) [32][33][34], we proceeded to the fitting of the numerical results based on the equations provided in [32][33][34] where the difference between both phenomena is highlighted. In the case when the transparency window is caused by ATS, the numerical spectrum is fitted by two Lorentzian lines having the same sign so as to signify the absence of Fano interferences.…”

“…So far, we have used an universal formula to analyze our observed coherence spectra and don't attribute these spectra into EIT or ATS, which are two extremes of threelevel coherent spectroscopy. Recently, investigating on discernment between EIT and ATS has become an active topic [37,38,[44][45][46][47][48][49]. Among these work, AIC is proposed to discriminate EIT and ATS from an experimental viewpoint [37].…”
