我们报告了高质量的InAs/InP量子点光放大器的1550 nm波长范围内工作在25至100摄氏度的宽温度范围。观察到峰值增益波长以0.78nm/K的速率随温度变化而漂移。因此，在整个温度范围内进行两种可能的操作模式，以进行系统的器件表征。在第一模式中，信号波长被调谐为总是与峰值增益波长匹配，而在第二模式中，信号波长保持恒定，因为增益谱随温度偏移。静态特性，如增益谱和饱和水平，以及动态特性，提出。一个单一的28 Gbit/s的信号和串扰放大的两个通道，失谐2 nm，失真少的放大，证明了在整个温度范围内。(C)根据OSA开放获取出版协议的条款，2017年美国光学学会
We report on high quality InAs/InP quantum dot optical amplifiers for the 1550 nm wavelength range operating over a wide temperature range of 25 to 100 degrees C. A temperature dependent shift of the peak gain wavelength at a rate of 0.78 nm/K is observed. Consequently, two possible modes of operation are performed for a systematic device characterization over the entire temperature range. In the first mode, the signal wavelength is tuned to always match the peak gain wavelength while in the second mode, the signal wavelength is kept constant as the gain spectrum shifts with the temperature. Static characteristics, such as gain spectra and saturation levels, as well as dynamical properties, are presented. Distortion-less amplification of a single 28 Gbit/s signal and cross-talk free amplification of two channels, detuned by 2 nm, were demonstrated over the entire temperature range.
