Abstract
【解決手段】 光ルーティングを行うための装置は、第1および第2の側面を有する金属層と、第1の側面に沿って位置付けされた規則的な配列の構造と、第1の側面の一部を照らすように位置付けされた入力光導波路とを含む。側面の照らされる部分は、上記構造のうちの構造に近接している。また、本装置は、入力光導波路で照らされない金属層の部分から放射される光を受け取るように位置付けされた複数の出力光導波路を含む。
【選択図】 図8
Description
Ksp(ω)=(ω/c)([εm(ω)εd]/[εm(ω)+εd])1/2u^
ここで、εm(ω)およびεdは界面4の2つの側の金属と誘電体の誘電率であり、cは光の速度である。光子の運動量Kの金属−誘電体海面4への投影Kr(ω)の分散関係は次式で与えられる。
|Kr(ω)|=(ω/c)(εd)1/2sin(θ)
投影|Kr|の大きさは、光子の入射角に依存する。
Gi−bj=2πδij
逆格子は、金属−誘電体界面4’での表面プラズモンの生成で役割を担う。
Ksp(ω)=Kp(ω)+rG1+sG2
ここで、「r」および「s」は整数であり、G1およびG2は、有限サイズの規則的な配列12に対する上記の逆格子ベクトルである。
