Spectral Hole Burning via Kerr Nonlinearity

Abstract

Spectral hole burning is investigated in an optical medium in the presence of Doppler broadening and Kerr nonlinearity. The Kerr nonlinearity generates coherent hole burning in the absorption spectrum. The higher order Kerr nonlinearity enhances the typical lamb dip of the hole. Normal dispersion in the hole burning region while Steep anomalous dispersion between the two hole burning regions also enhances with higher order Kerr effect. A large phase shift creates large delay or advancement in the pulse propagation while no distortion is observed in the pulse. These results provide significant steps to improve optical memory, telecom devices, preservation of information and image quality.

Incoherent and coherent manipulation of surface plasmon hole burning

“…Spectral hole burning [25][26][27], a phenomenon in which a saturating field burns a hole into the population distribution of a nonlinear medium, has been reported in different atomic systems using Doppler broadening and/or Kerrnonlinearity.…”
