Keywords:

Semiconductor lasers,optical amplifiers,and light emitting diodes,Quantum well,quantum dot,and nano-structured photonic devices

We propose a surface-emitting laser design featuring optimized epitaxial structure for effective current injection and simplified fabrication process, and topological photonic crystal cavity enabling large mode spacing and coherent lasing units.
