A profile of an optical diode is derived from a topology optimal structure obtained in our previous study, and it is simplified so as to reduce insertion loss and difficulty in fabrication. An optimal profile is found out using a differential evolution (DE) which is one of the evolutionary algorithms, and optimization is carried out taken into account fabrication tolerance. According to the results of numerical simulation by 2D finite element method (FEM), the optimized plasmonic optical diode has insertion loss of <0.5 dB, reflection of <-20 dB in the forward propagation, and backward transmission of <-20 dB over C-band, and it is tolerant of ±5 nm boundary deviation. In addition, this device has an extremely small functional region (<1.5 μm).","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_79_link_17":{"attribute_name":"出版者版へのリンク","attribute_value_mlt":[{"subitem_link_text":"10.1587/elex.16.20190598","subitem_link_url":"https://doi.org/10.1587/elex.16.20190598"}]},"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":"井口
