| 摘 要： | 利用耦合波方程,对两段式DFB激光器进行理论分析,得出了激光器激射工作时两段载流子浓度和激射波长之间所满足的隐含表达式。作为特例,分析了吸收型器件在两段等长情况下的阈值载流子浓度变化和波长调谐特性。

| Abstract: | Based on coupling-wave equation,two-segment DFB lasers have been analyzed,and implicit expression of their carrier density and emission wavelength has been obtained.As a special case,the oscillation behaviors of the absorptive device with two equal-length segments:threshold conditions,carrier density and wavelength tuning range have been analyzed. |

| Keywords: | two-segment DFB semiconductor lasers carrier density wavelength tuning |
