Crystal growth, structure and thermal property of new magneto-optical thin film substrates CLNGG and LCLNGG

Translated Abstract

Magneto-optical　film　has　a　good　application　prospect　for　integrated　optical　devices　[1].With　the　development　of　optical　communication　technology,some　new　performance　and　quality　requirements　for　the　film　are　raised.The　lattice　constant　of　CLNGG　is　well-matched　with　Ce:YIG,expected　to　be　used　as　the　substrate　material　for　obtaining　high　quality　Ce:YIG　film.In　this　paper,CLNGG(Ca2.899Li0.304Nb1.926Ga2.757O12)and　Li5La3Nb2O12　doped　CLNGG(Ca2.382La0.568Li0.72Nb2.005Ga2.262O12,LCLNGG)crystal　were　grown　by　Czochralski　method,the　effect　of　growth　conditions　and　annealing　process　on　the　quality　and　transmission　performance　of　the　crystals　were　discussed.By　using　Rietveld　method,the　structures　were　refined,and　the　effect　of　doping　ions　on　the　structure　were　also　discussed.The　thermal　expansion　coefficients　of　CLNGG　and　LCLNGG　were　measured　as　5.83×10-6K-1and　5.62×10-6K-1,respectively,close　to　that　of　YIG[2].All　these　results　indicated　that　CLNGG　and　LCLNGG　crystals　are　good　candidate　substrate　for　Ce-doped　iron　garnet　film.
