Carrier-frequency dependence of a step-modulated pulse propagating through a weakly dispersive single narrow-resonance absorber

Published

Journal Article

We observe interference between the optical precursors and the main signal for small optical depth α0L∼1, in which the main signal cannot be entirely absorbed. Since the main signal oscillates at the carrier frequency of the input pulse and precursors oscillate at medium resonance frequency, in our case carrier frequency dependence of the total transmitted field is observed as a form of modulation patterns oscillating at the detuning frequency. To distinguish between the Sommerfeld and Brillouin precursors for the case of weakly dispersive off-resonance medium, we utilize asymptotic precursor theory under the assumption of small detuning. © 2011 Taylor & Francis.
