奈米相變化記錄點的近場光學耦合效應

Near-field Optical Coupling between Nano Recording Marks in phase-change Material

摘要


相變化材料是一種可藉由光-熱效應來改變本身晶格狀態與光學特性的物質,已普遍地被應用於各種光儲存媒介中,本文將以時域有限差分法計算不同幾何形貌的奈米相變化記錄點之近場光學耦合效應,並討論其對讀取反射光訊號的影響。

並列摘要


The three-dimensional finite-difference time-domain method is used to investigate surface plasmon polariton coupling between phase-change nano-recording marks which are of different shapes. The different coupling characteristics and the influence of these coupling effects on the read-out reflection signal are discussed.
