复合光子构造元件、使用该复合光子构造元件的面发光激光器、波长变换元件、具有该波长变换元件的激光加工装置
摘要：
复合光子构造元件具有光子晶体以及多层膜。光子晶体是交替层叠多组具有将基波变换为第二谐波的非线性效应的活性层、和不具有非线性效应的非活性层而形成的，构成为使基波的能量与光子带隙端一致。多层膜是层叠多组折射率不同的2种薄膜而形成的，反射基波。多层膜与光子晶体的两侧接合。通过从一侧的端面入射基波，且使基波在具有多层膜的谐振器之间往复反射，由此，使光子晶体内部的基波的强度增强。在活性层中，将基波变换为第二谐波，将第二谐波从另一侧的端面向外部取出。
摘要（英）：

A composite photonic structure element includes a photonic crystal and a multi-layer film. The photonic crystal is formed by alternately laying an active layer having a nonlinear effect for converting a fundamental wave into a second higher harmonic and an inactive layer having no nonlinear effect, so that the energy of the fundamental wave coincides with the photonic band gap end. The multi-layer film is formed by layering a plurality of sets of two types of thin films having different refractive indexes so as to reflect the fundamental wave. The multi-layer film is connected to both ends of the photonic crystal. The fundamental wave comes into one of the end faces and the fundamental wave is reciprocally reflected between resonators having a multi-layer film so that the intensity of the fundamental wave in the photonic crystal is increased. The fundamental wave is converted into a second higher harmonic in the active layer and the second higher harmonic is extracted outside from the other end face.
