波のみに対して検討されている．近年，強導波路を用いたデバイスの小型化が盛んに検討されるなか，偏波無依存化や偏波分離といった偏波の違いを考慮した設計もまた重要になっている．本研究では，関数展開法に基づくトポロジー最適設計法をTE，TM 両方の偏波に対して適用し，小型な偏波分離素子の設計について検討を行っている．本検討では，数値解析に有限要素法，感度解析に随伴変数法を用いている．","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_79_link_5":{"attribute_name":"室蘭工業大学研究者データベースへのリンク","attribute_value_mlt":[{"subitem_link_text":"辻
