Abstract
Electro-optic modulation is demonstrated in 10-mu m-thick single-crystal Li NbO3 films obtained by crystal ion slicing. This technique uses ion implant ation of single-crystal bulk samples followed by selective etching. The mea sured electro-optic response of these films is comparable, within experimen tal error, to that of single-crystal bulk LiNbO3 and is superior to previou sly reported values for epitaxial polycrystalline thin films. The product o f half-wave voltage and modulator length, VpiL, is 8 V cm. Post lift-off an nealing is shown to be of key importance in improving the modulator extinct ion ratio.
