Congruent or stoichiometric $LiNbO_3$ fiber single crystals were grown by the $mu$-PD method, and the grown fiber crystals have the several (2 or 3) ridges with a diameter of $1.35{sim}1.5;mm$ and a length of $40{sim}100;mm$. In this $mu$-PD process, different growth rates ($10{sim}60;mm/h$) were applied. Pt wire or $LiNbO_3$ crystal was used as a seed. The properties of grown $LiNbO_3$ fiber single crystals having a-axis or c-axis according to seeds were effected by the grown conditions(Pt tube diameter, pulling speed, after heater etc.). Disk-type $LiNbO_3$ samples were poled in condition of DC 5 V/cm at 1050, 1075 or $1100^{circ}C$. XRD, SEM, conoscope image through the polarized microscope, $T_C$ measuring apparatus, optical transmittance measuring instrument are used to identify the properties of $LiNbO_3$.
Key words: Lithium niobate ($LiNbO_3$), $\mu$-PD method, Fiber single crystals, Ridge, Poling
