光子晶體異質結構共振腔有極高的品質因子以及和低損耗的光子晶體波導結合。在積體光路,這種元件在很多應用上已經吸引了極大的注意。由於量子點的零維的局限特性,使其可以減少臨界電流降低、溫度的相依性,以及較高的微分增益。我們簡單地調變光子晶體波導中間區域洞的數目以及往外移動距離來形成光子晶體異質結構共振腔。在製程上會比較容易製作。我們結合這些好處在砷化銦薄板上製作成光子晶體異質結構雷射。
Photonic crystal heterostructure cavity has ultra high Q factor and integrates with a low loss photonic crystal waveguide. In photonic integrated circuits, this element has attracted much attention in many application. Owing to the zero-dimensional confinement properties, quantum dots can reduce the threshold current, lower the temperature dependence, and higher differential gain. The photonic crystal heterostructure cavities are formed by simply adjusting numbers of holes in the central region in the waveguide and shifting the holes away from the waveguide by distance. It is easy for fabrication. In the thesis, we integrate these benefits in a photonic crystal heterostructure laser in a InAs membrane.
