平面有源区隐埋异质结(BH)激光器光-电流特性的非线性与高阶模变换、光谱展宽有关,在某些情况下还与 TM 偏振受激发射的开始有关。该文介绍了测量和计算的情况并指出,在减小了有源体积的器件中,在较高的功率下出现这些非线性。这些结果对于用在高比特速
The nonlinearity of the light-current characteristics of buried active (Hb) lasers in planar active regions is related to higher-order mode transforms and spectral broadening and in some cases to the onset of TM polarized stimulated emission. This paper describes the measurement and calculation cases and points out that these nonlinearities occur at higher powers in devices with reduced active bulk. These results are for high bit rates
