Web8 apr. 2024 · The manipulation of light at the nanoscale is important for nanophotonic research. Lithium niobite (LiNbO3), as an ideal building block for metamaterials, has attracted great interest for its unique properties in the field of nonlinear optics. In this paper, we numerically studied the effect of different substrates on the optical resonances of a … WebLithium niobate (LiNbO 3) is a ferroelectric crystal that belongs to the trigonal crystal system. Lithium niobate is transparent between 0.25 and 5.3 μm (fig. 1). It can be used in visible, near IR and middle IR region. Fig. 1. Transmittance spectrum of lithium niobate.

WebThe 2-D matrix describes the non-susceptibility tensor χ(2). For 5% MgO doped lithium niobate (MgO:LN) at 1064nm, d31=4.4pm/V, d33=25pm/V [1]. The highest nonlinear coefficient is d33=25pm/V, which corresponds to interactions that are parallel to the z-axis, i.e. type-0 phase matching. WebNanocrystalline compounds LiNb1−xTaxO3 of various compositions (x = 0, 0.25, 0.5, 0.75, 1) were synthesized by high-energy ball milling of the initial materials (Li2CO3, Nb2O5, Ta2O5) and subsequent high-temperature annealing of the resulting powders. Data on the phase composition of the nanopowders were obtained by X-ray diffraction methods, and … links in youtube description
