Description

また、第３および第４のカバー９９および１００は、第１および第２のカバー９７および９８と同一の屈折率を有するクラッド材料で構成されており、第３および第４の導波路コア９５および９６の中に光を閉じ込めて伝播させるためのクラッドとして機能する。この点で、クラッドとして機能しない図１における第１および第２のガイド７１および７２とは異なる。
なお、図６において、第３および第４のカバー９９および１００は、第１および第２のカバー９７および９８を左右方向から挟み込むように構成されている。しかし、第３および第４のカバー９９および１００の上下方向の長さを短くして、第１および第２のカバー９７および９８によって上下方向から挟み込まれるように構成されてもよいし、これらを含む構成部全てが一体的に形成されていてもよい。
