Fa'amatalaga Puupuu ole Lithium Niobate Crystal ma Ona Fa'aoga - Vaega 4: Fa'alatalata-Stoichiometric Lithium Niobate Crystal

Faatusatusa imasani LNtioata(CLN)faʻatasi ai ma le tuʻufaʻatasiga tutusa, le leai o le lithium i le lata mai-stoichiometricLNtioata(SLN)e taʻitaʻia ai se faʻaitiitiga tele o faʻaletonu lattice, ma le tele o meatotino e suia e tusa ai.O lo'o lisiina i lalo le laulau autueseesega omeatotino faaletino.

Faatusatusa iCLNfaatasi ai ma le tuufaatasiga tutusa, le tele o meatotino oSLNua faaleleia i tulaga eseese.O le sili atu ona taua optimization e aofia ai:

(1) Wether photorefractive doping, anti-photorefractive doping po'o le laser-activated ion doping,SLN iaie sili atu ona maaleale aafiaga o tulafono faatonutonu.Kong et al.maua ai e faapea a oo atu le [Li]/[Nb] i le 0.995 ma o le magnesium o loo i totonu o le 1.0mol%, o le tetee o le photorefractive o leSLNe mafai ona o'o i le 26 MW/cm2, o le 6 poloaiga o le maualuga maualuga atu nai lo leCLNma le fatuga tutusa.Photorefractive doping ma leisa-activated ion doping e iai foi aafiaga tutusa.

(2) E pei o le numera o lattice faaletonu iSLNtioata fa'aitiitia tele, e fa'apea fo'i le malosi fa'amalosi o le tioata, ma o le voltage e mana'omia mo le suiga o le polarization e fa'aitiitia mai le 21 kV/mm.(o le CLN)e tusa ma le 5 kV/mm, lea e aoga tele mo le saunia o masini superlattice.E le gata i lea, o le fausaga o le vaega eletise oSLNe sili atu ona masani ma o puipui o le fanua e lamolemole.

(3)Tele photoelectricmeatotino aSLNua matua faaleleia foi, e pei o le electro-optic coefficientr61si'itia i le 63%, fa'asili nonlinear si'itia i le 22%, tioata birefringence si'itia e 43% (umi galu 632.8 nm), sifi lanumoanao le UVpito miti, ma isi.
