使用 d33 非线性系数，在平面和通道钽酸锂 (LiTaO3) 退火质子交换波导中通过准相位匹配二次谐波生成在室温下产生蓝光。通过用周期性电场极化衬底来创建用于三阶准相匹配的交替铁电域。
Blue light was generated at room temperature by quasiphase-matched second harmonic generation in planar and channel lithium tantalate (LiTaO3) annealed proton exchange waveguides using the d33 nonlinear coefficient. Alternating ferroelectric domains for third order quasiphase matching were created by poling the substrates with a periodic electric field.
