Abstract

【課題】　簡単な構成で、２以上の導光路が交差する光量損失をこれまで以上に少なくすることを可能とした交差型導光路を提供すること。 【解決手段】　第１の導光路１１の入射側導光路１１Ａの幅寸法ｄと射出側導光路１１Ｂの幅寸法ｄに対し、第１の導光路１１の射出側導光路１１Ｂの幅寸法Ｗ１および射出側導光路１１Ｂの幅寸法Ｗ２がｄ＜Ｗ１＝Ｗ２に設定されている。第１の導光路１１では入射側導光路１１Ａから射出され、前記交差点１３を介して伝搬される光の殆どは、漏れなく射出側導光路１１Ｂで取得され、第２の導光路１２では入射側導光路１２Ａから射出され、前記交差点１３を介して伝搬される光の殆どは、漏れなく射出側導光路１２Ｂで取得される。このため、光量損失を大幅に低減することが可能となる。
