摘要： In a coarse wavelength division multiplexing (CWDM) optical transmission system, a distributed feedback (DFB) laser is tuned so that the peak reflection of the grating overlaps with the gain range of the DFB laser. The diffraction grating is tuned so that the peak is positioned on the long wavelength end of the gain spectrum at a selected temperature. The optical transmission system operates in an environment having a wide temperature range (i.e., about -40°C to about 85°C). Heat is applied to the laser and as the laser temperature increases, the gain range overtakes the grating peak. When the gain range and the grating peak overlap at increased laser temperature, laser output is improved.
摘要翻译：在粗波分复用（CWDM）光传输系统中，分布式反馈（DFB）激光器被调谐，使得光栅的峰值反射与DFB激光器的增益范围重叠。调整衍射光栅，使得峰位于选定温度下的增益谱长波长端。光传输系统在宽温度范围（即约-40℃至约85℃）的环境中工作。对激光施加热量，随着激光温度的升高，增益范围超过光栅峰值。当增益范围和光栅峰值在增加的激光温度下重叠时，激光输出得到改善。
