Patent number: 10908356Abstract: An optical circuit board which is mounted with a loop-back circuit for returning aligning light to the fiber array in the vicinity of the fiber array connection end. Since an aligning loop-back circuit can be formed in an optical waveguide pattern, a production cost does not increase in comparison to an optical circuit board of the related art. The aligning light combined from the optical fiber to the aligning port of the optical circuit board is returned to the optical fiber around the loop-back circuit. Therefore, it is possible to perform alignment using the returned light. That is, alignment can be performed while being mounted on a package without installing a light-reflecting film or mirror.Type: GrantFiled: November 2, 2017Date of Patent: February 2, 2021Assignees: NTT ELECTRONICS CORPORATION, NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Tomohiro Nakanishi, Motoki Minami, Satoru Konno, Yuichi Suzuki, Teruaki Sato, Shigeo Nagashima, Shinji Mino, Motohaya Ishii, Shunichi Soma, Shin Kamei, Shuichiro Asakawa
