Abstract
Description
図1は本実施形態の光波長合分波器の構成を示す図である。本実施形態の光波長合分波器は、波長数(チャネル数)がN、チャネル周波数間隔Δf(GHz)の多重光信号を波長λNごとの光信号に分波するものとして説明する。本実施形態の光波長合分波器1は、図1に示すように、第1の入出力導波路10と、第1のスラブ導波路20と、アレイ導波路30と、第2のスラブ導波路40と、第2の入出力導波路50とを備えた、いわゆるAWGにより構成される。第1の入出力導波路は、2つの入出力12、13に分岐されており、2つの入出力12、13は2つのパラボラ導波路14、15を介して第1のスラブ導波路20の所定の位置に接続している。また、第2の入出力導波路50は2つの導波路群51、52により構成されており、2つの導波路群51、52は第2のスラブ導波路40の所定の位置に接続している。第2のスラブ導波路40に接続する部分の第2の入出力導波路50は直線導波路であるが、図4(b)の従来構造の例のようにテーパー導波路でも良い。
第1の実施形態の説明では、入力導波路の2つの入力と第1のスラブ導波路との間にパラボラ導波路を設けた構成について説明した。しかしながら、このパラボラ導波路を設けず、入力導波路の2つの入力と第1のスラブ導波路とを直接接続した構成としてもよい。
