本論文利用串聯式分佈反饋雷射為基礎設計多波長雷射陣列，以應用於光學感測系統。藉由合作廠商代工完成具不同布拉格波長之雷射陣列，以涵蓋較寬的波長範圍。藉由使用不同的雷射端面鍍膜與調控不同的注入電流探討雷射操作模式與輸出效能，目標為在利用溫度調動波長時能使所有雷射達成穩定的單模輸出結果。

This work aims to develop multi-wavelength laser arrays based on cascaded distributed feedback (DFB) lasers for using as tunable lasers in optical sensing systems. With the help of foundry services, the laser array including multiple DFB lasers of different Bragg wavelengths were realized to cover a wide wavelength range. Different facet coatings and injection currents are applied to the laser arrays to investigate the effects on the laser operation and output performance. The goal is to obtain single-mode operation for all lasers in an array under the thermal tuning to address all wavelengths.
