本研究では,3次元中空光導波路による巨大な可変伝搬特性を実現するとともに,その光回路への応用を目指して研究を進め,以下の成果を得た.(1)3次元中空光導波路の偏光特性制御3次元中空光導波路の偏光依存性を検討し,ステップ構造の深さ制御により,偏光依存性を拡大できることを見出し,実際に製作してスラブ型中空導波路に比べて2倍以上の大きな値を得た.(2)テーパ型中空光導波路を用いた偏波分散補償器の提案と実証大きな偏光依存性を有する3次元中空光導波路を用いて表面回折格子とテーパ構造を導入することで,可変の偏波分散補償機能を実現できることを提案し,実際に試作して長さ3mm程度の微小回路で,約10psecの偏波分散を実現した.(3)サブ波長高屈折率差回折格子を用いた新しい3次元中空光導波路の提案と製作広帯域・高反射率を可能とするサブ波長高屈折率差回折格子を反射鏡とする新しい3次元中光導波路を提案し,小さな偏光依存性と,部分パターン化による簡易な2次元光閉じ込め機能が実現できることをモデリングにより示すとともに,実際に電子ビーム露光とドライエッチングによりSiサブ波長高屈折率差回折格子を製作して3次元中空導波路を製作し,2次元光閉じ込め,4dB/cm程度の伝搬素損失,小さな偏光依存性を実証した.

In this paper, the research on the application of three-dimensional hollow optical waveguide has been carried out, and the following results have been obtained. (1)3 The polarization dependence of three-dimensional hollow waveguide is studied. The polarization dependence of three-dimensional hollow waveguide is increased. In fact, the polarization dependence of three-dimensional hollow waveguide is increased by more than 2 times. (2)A polarization dispersion compensator for a three-dimensional hollow optical waveguide is proposed. The polarization dispersion compensator can be realized by introducing a three-dimensional hollow optical waveguide with a surface folding lattice structure. The polarization dispersion compensator can be realized by a small circuit with a length of about 3mm and a polarization dispersion of about 10psec. (3)A new three-dimensional optical waveguide with high refractive index difference is proposed for use as a mirror. A new three-dimensional optical waveguide with high refractive index difference is proposed for use as a mirror. A new three-dimensional optical waveguide with high refractive index difference is proposed for use as a mirror. In fact, the electron beam exposure and high refractive index difference of Si wavelength are produced. The 3D hollow waveguide is produced. The 2D optical closure is produced. The transmission loss of 4dB/cm is realized. The polarization dependence is small.
