摘要	A tunable semiconductor laser comprises a gain section having an MQW active region, a uniform pitch grating DFB region, and first waveguide. A composite reflector, including a second MQW region and a second waveguide, forms a cavity resonator with the DFB region. A tuning voltage applied to the composite reflector induces a quantum confined stark effect, thereby allowing the center wavelength to be altered. A pre-chirp signal applied the composite reflector reduces signal distortion in fiber optic systems.
其他摘要	可调谐半导体激光器包括增益部分，该增益部分具有MQW有源区，均匀间距光栅DFB区和第一波导。包括第二MQW区域和第二波导的复合反射器与DFB区域形成空腔谐振器。施加到复合反射器的调谐电压引起量子限制的斯塔克效应，从而允许改变中心波长。应用复合反射器的预啁啾信号减少了光纤系统中的信号失真。
