從光纖通訊到醫療娛樂，雷射二極體於我們的生活中無所不在，然而許多雷射二極體的應用者，對於其工作原理理解也相當有限。本課程上半部將從基礎的量子與固態物理出發，探討半導體內光子與載子的交互作用機制與複合效率。並描述半導體在非平衡態的情形下，如何達到時態穩定的光學增益(optical gain)效果。下半部將探討二極體雷射的元件特性，解釋二極體雷射是如何透過設計達到各種需求的功能性，成為市場上常見的各種二極體雷射，諸如邊射型雷射，VCSEL，DBR，DFB雷射等。 This course aim to understand the physics and working principles of common semiconductor laser diodes. The first part will cover the fundamental of semiconductor physics in non-equilibrium state. We will explain the interaction between confined photon and carriers in the materials, and how the steady-state stimulated emission, a.k.a. lasing, can be achieved in a semiconductor cavity. The second part will introduce the working principle of typical semiconductor structure, such as, edge-emitting lasers, VCSEL, DBR and DFB lasers. This course will cover most of the textbook from chapter 1~chapter 4, and Appendix 1 to 7.
