Heterostructure and Q-factor engineering for low-threshold and persistent nanowire lasing
Heterostructure and Q-factor engineering for low-threshold and persistent nanowire lasing is a scholarly work by H Aruni Fonseka, Ana M. Sanchez, Patrick Parkinson, and Huiyun Liu, published in 2020 in ''Light: Science & Applications''. The main subjects of the publication include materials science, optics, silicon photonics, quantum dot, heterojunction, silicon, optoelectronics, nanowire, semiconductor laser theory, laser, spontaneous emission, Nanolaser, population inversion, Gain-switching, and Lasing threshold. The authors apply time-gated optical interferometry to the lasing emission from high-quality GaAsP/GaAs quantum well nanowire laser structures, revealing high Q-factors of 1250 ± 90 corresponding to end-facet reflectivities of R = 0.73 ± 0.02.
