[25p-D315-4] ドーピング構造設計最適化による3~4THz帯QCLのワットクラス高出力化
キーワード:量子カスケードレーザー
A 1.31 W peak power and 52 mW average power THz quantum cascade laser (QCL) is presented by variable Al composition active structure with high doping concentration based on Non-Equilibrium Green Function (NEGF) method design.Device has thick growth active layers and large mesa size with the consideration of heat dissipation.
