摘要

提出并论证了DFB MQW单模激光器的新概念。新结构结合了高SMSR、优异的均匀性、高效率和低发散。均匀的光谱性能在3mw的SMSR为44 dB时得到了证明，表明标准的加工技术可以用于制造具有均匀性能的单模器件，并且理论产率与Fabry-Perot激光器相似，达到100%。阈值低至14 mA，效率为0.32 W/A，发散度为14°×16°。这些结果非常有希望，为WDM应用中具有高度竞争性性能的无选择单模激光器的制造开辟了道路。

New WDM DFB laser structure for facet phase-free uniform performances

A new concept for a DFB MQW monomode laser has been proposed and demonstrated. The new structure combines high SMSR, excellent uniformity, high efficiency and low divergence. Uniform spectral performances have been demonstrated with a SMSR of 44 dB at 3 mW, showing that standard processing techniques can be used to fabricate monomode devices with uniformity performances and a theoretical yield of 100% similar to that of Fabry-Perot lasers. Threshold as low as 14 mA, an efficiency of 0.32 W/A and a divergence of 14°×16° could also be obtained with the proposed principle. These results are very promising and open the way for the fabrication of selection-free monomode lasers for WDM applications with highly competitive performances.
