采用一种新的方法控制超快激光刻写BiB（3）O（6）波导中正交线偏振波导模的空间重叠。我们报告的应变场引起的材料在激光焦点的膨胀可以被认为是独立的“II型”波导引导正交线偏振光的设计。将具有最佳模式重叠的波导用于1047 nm连续波激光源的I型互补相位匹配二次谐波产生。
A novel technique was used to control the spatial overlap of the orthogonal linearly polarized waveguide modes in ultrafast laser inscribed BiB(3)O(6) waveguides. We report that the strain fields induced by the expansion of material in the laser focus can be considered independently in the design of "type II" waveguides guiding orthogonal linearly polarized light. The waveguide with the optimal mode overlap was used for type I birefringently phase-matched second-harmonic generation of a continuous wave laser source at 1047 nm.
