我们发现 325 nm He-Cd 激光照射使 LiNbO3 晶体的电阻率降低了大约 3 个数量级。而且,在该UV光照射下,证明与非UV光照射的情况相比,可以将畴反转的阈值电压降低至30%。利用这项技术,我们首次在低电压下成功形成了小于 1 µm 的微小畴反转。
We found that 325 nm He–Cd laser light irradiation reduces the resistivity of LiNbO3 crystals by approximately 3 orders of magnitude. Moreover, under this UV light irradiation, it was proved that the threshold voltage for domain inversion can be reduced to 30% as compared with the case of non-UV light irradiation. Using this technique, we successfully formed a minute domain inversion of less than 1 µm at a low voltage, for the first time.
