摘要

我们展示了一种抑制直接调制DFB激光器非线性畸变的新方法。在我们的方案中，外部激光注入到DFB激光器的侧模中。使用该方案，我们显著降低了非线性失真，如二次谐波失真(SHD)、二阶互调失真(IMD2)和三阶互调失真(IMD3)。此外，我们还增强了外部光的失谐范围。

Nonlinear distortion suppression in directly modulated DFB lasers by sidemode optical injection

We demonstrate a new method of suppressing nonlinear distortions in directly modulated DFB lasers. In our scheme, external laser light is injected into the sidemode of the DFB laser. Using this scheme, we achieved significant reduction in nonlinear distortions such as the second harmonic distortion (SHD), second order intermodulation distortion (IMD2), and third order intermodulation distortion (IMD3). In addition, we enhanced the external light detuning range.
