Nd-doped LiNbO 3 (Nd : LiNbO 3 ) thin film with c -axis preferred orientation has first been fabricated on a SiO 2 /Si(1 1 1) substrate by pulsed laser deposition. A smooth surface and a sharp interface have been affirmed by scanning probe microscopy and transmission electron microscopy, respectively. The fluorescence at around 902.5, 1087.5 and 1379.3 nm was excited with a diode laser at 808 nm, and the optical and spectral characteristics and waveguide behaviours were investigated as well. The results show that the highly c -axis oriented Nd : LiNbO 3 thin film on SiO 2 /Si(1 1 1) substrate may have actual application in integrated optics.
