d型硅纤维在高温下周期性极化，通过在平面侧沉积的图案化电极施加高压。所得到的周期为25µm的非线性光栅，在整个1.8cm长度上均匀，用于准相位匹配的二次谐波产生。以锁模激光器为基源，在~422nm处产生了~76 μ W的蓝光功率，平均转换效率为~0.22%。
D-shape silica fibres have been periodically poled at elevated temperature by applying high voltage via a patterned electrode deposited on the plane side. The resulting nonlinear grating of 25µm period, uniform over the whole 1.8cm length, has been used for quasi-phase-matched second harmonic generation. With a mode-locked laser as fundamental source blue powers up to ~76µW have been generated at ~422nm with an average conversion efficiency of ~0.22%.
