论文摘要
在外延生长的半导体膜量子量子井中的波导几何形状中证明了与硅光子兼容的相干激光阵列在碳化硅碳化物和氧化硅的底物上转移的。我们将激光阈值低至60兆瓦的泵功率。我们研究了亚MM范围内的单个激光器和激光阵列的发射。我们能够使用真实和相互的空间成像创建大约5-10μm的模态宽度的波导激光阵列,我们研究了它们的发射特性,并发现它们在每个激光器上以单个或多个纵向模式进行操作,并发现它们保持相互的连贯性。
Coherent laser arrays compatible with silicon photonics are demonstrated in a waveguide geometry in epitaxially grown semiconductor membrane quantum well lasers transferred on substrates of silicon carbide and oxidised silicon; we record lasing thresholds as low as 60 mW of pump power. We study the emission of single lasers and arrays of lasers in the sub-mm range. We are able to create waveguide laser arrays with modal widths of approximately 5-10 μm separated by 10-20 μm, using real and reciprocal space imaging we study their emission characteristics and find that they maintain their mutual coherence while operating on either single or multiple longitudinal modes per lasing cavity.
