Abstract
Description
スルーホールは任意の好適な形状(例えば長方形)を有していてもよい。また、マイクロ構造体は、導波路内に設けられたさまざまな種類のマイクロ構造体の組み合わせ、例えば、導波路内で完全に設けられたもの(例えばスルーホール)または部分的に設けられたもの(例えばくぼみ)であってもよい。パターンは規則的なパターンであってよい。本発明の実施形態では、そのパターンは、導波路から出射した光信号がグレーティングカプラを通じて伝搬するときに生じる減衰を補償するように構成されている。このように構成されたパターンにより、生成する光円錐の均一性が向上し、これにより、規則的なパターンを用いる場合と比べて大きいピンホールを利用できる。オブジェクトの照明に用いる光のエネルギーを大きくして、オブジェクトをより良好に照明できることは好都合である。
