| 摘 要： | F-P半导体激光器中对于TE模比TM模有更大的束缚系数,并且在其反射面上有更高的反射率.当TE模和TM模同时注入F-P半导体激光器的谐振腔时,TE模方向的信号得到增长,TM模方向的信号受到抑制.F-P半导体激光器的这种特性使得它类似于一个偏振器,但是其优越之处在于经过F-P半导体激光器注入锁定之后的光信号没有功率损耗.采用F-P半导体激光器的注入锁定原理,使入射光信号没有功率损耗地由偏振光转换为部分偏振光,降低了通信系统中传输信号的偏振敏感性,使传输信号的质量得到提高,实现了F-P半导体激光器三波长和四波长注入锁定. |
| 关 键 词： | F-P半导体激光器 偏振敏感性 多波长注入锁定 功率损耗 |

| Abstract: | TE mode has larger cord coefficient and reflective index than TM mode in Fabry-Perot laser diode, when they realize injection locking without power less. The signal from TE mode increases, meanwhile,the signal from TM mode decreases. This character makes Fabry-Perot laser diode like a polarizer. Using the principle of injection locking for Fabry-Perot laser diode, we transfered the polarized light into part polarized light, reducing the polarization sensitivity for the transmission signal, improving the quality of the transmission signal. Besides, multi-wavelength injection-locking was demonstrated by using Fabry-Perot laser diode for the first time. |
| Keywords: | Fabry-Perot laser diode Polarization sensitivity Multi-wavelength injection-locking Power less |
