Efficient Quasi-Resonant, Polarization-Selective Excitation of GaN Quantum Emitters
Nilesh Dalla, PaweÅ Kulboka, MichaÅ Kobecki +6
Defect centers in GaN emerge as bright sources of single-photons which recently have been demonstrated to optically interface a localized spin. However, the structure and compositi…

Edge emission from 265~nm UV-C LEDs grown by MBE on bulk AlN
Shivali Agrawal, Hsin-Wei S. Huang, Debaditya Bhattacharya +6
UV-C LEDs pseudomorphically grown by MBE on bulk AlN substrates emitting at 265 nm are demonstrated. High current density up to 800 A/cm, 5 orders of on/off ratio, and low diff…

Off-resonant photoluminescence spectroscopy of high-optical quality single photon emitters in GaN
Nilesh Dalla, PaweÅ Kulboka, MichaÅ Kobecki +5
In this work, we analyze the relevance of excitation parameters on the emission from single-photon emitting defect centers in GaN. We investigate the absorption spectrum of differe…
