The dielectric behaviour of doped near-stoichiometric lithium niobate in the terahertz range

doi:10.1088/1674-1056/21/1/017802

Abstract The dielectric properties of near-stoichiometric LiNbO₃:Fe and LiNbO₃:Ce single crystals have been investigated using terahertz time domain spectroscopy in a frequency range of 0.7-1.6 THz at room temperature. When coupled with an applied external optical field, obvious photorefractive effects were observed, resulting in a modulation of the complex dielectric constant for the crystals. The variation in refractive index, |Δn|, had a linear relationship with the applied light intensity, accompanied by a step-like decrease at high intensity. The findings were attributed to the internal space charge field of the photorefraction and the light-induced domain reversal in the crystals.

Keywords: near-stoichiometric LiNbO₃ terahertz photorefraction domain reversal
