设计并制作了970 nm反射式垂直腔半导体光放大器(VCSOA)
基于放大器结构
对放大器的噪声特性、增益和带宽特性进行了实验研究和理论分析。研究了反射式放大器的增益与垂直腔半导体激光器出光口径的关系
发现增益随着出光口径的增大而增大。对于970 nm的信号光
经过出光口径为400 m的VCSOA后
最高获得了26 dB的增益放大
带宽为25 GHz。理论计算的过剩噪声系数和实验值之间有较好的符合关系
当底面和顶面的反射率分别为0.99和0.98时
放大器的噪声因子为6.6。
The 970 nm reflection-mode vertical cavity semiconductor optical amplifiers (VCSOA) were designed and fabricated. Based on the structure of VCSOA
the amplifier noise
gain and bandwidth characteristics were experimentally investigated and analyzed in the reflection mode. For a signal light of 970 nm
the maximum of gain amplification can reach to 26 dB after VCSOA. The bandwidth is 25 GHz when the gain is 26 dB. The noise factor is 6.6 when the bottom and top reflectivity is 0.99 and 0.98
respectively.
