| 摘 要： | 本文从理论上分析了外部光反馈对强耦合外腔半导体激光器特性的影响，对相干外部光反馈和非相干外部光反馈两种情形的分析结果均表明强耦合外腔半导体激光器可将半导体激光器所能容忍的临界光反馈强度提高大约２０ｄＢ以上，同时得出了长外腔和强耦合有利于提高外腔半导体激光器抗反馈能力的结论。

| Abstract: | Effect of external optical feedback on strongly coupled external cavity semiconductor laser is theoretically analyzed for both coherent and incoherent external optical feedback. The results show that the critical tolerable level of external optical feedback can be greatly increased by about 20dB for strongly coupled external cavity semiconductor laser compared to solitary laser diode.It is also obtained that long external cavity length and strong external cavity coupling are beneficial to resist feedback for external cavity semiconductor lasers. |
