Efficient Quasi-Resonant, Polarization-Selective Excitation of GaN Quantum Emitters
Nilesh Dalla, Paweł Kulboka, Michał 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…
Off-resonant photoluminescence spectroscopy of high-optical quality single photon emitters in GaN
Nilesh Dalla, Paweł Kulboka, Michał 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…
Giant photoelasticity of polaritons for detection of coherent phonons in a superlattice with quantum sensitivity
Michal Kobecki, Alexey V. Scherbakov, Serhii M. Kukhtaruk +7
The functionality of phonon-based quantum devices largely depends on the efficiency of interaction of phonons with other excitations. For phonon frequencies above 20 GHz, generatio…
Accumulation and control of spin waves in magnonic dielectric microresonators by a comb of ultrashort laser pulses
A. E. Khramova, M. Kobecki, I. A. Akimov +7
Spin waves in magnetic microresonators are at the core of modern magnonics. Here we demonstrate a new method of tunable excitation of different spin wave modes in magnetic microdis…
Picosecond Ultrasonics with Miniaturized Semiconductor Lasers
Michal Kobecki, Giuseppe Tandoi, Eugenio Di Gaetano +8
There is a great desire to extend ultrasonic techniques to the imaging and characterization of nanoobjects. This can be achieved by picosecond ultrasonics, where by using ultrafast…
Resonant thermal energy transfer to magnons in a ferromagnetic nanolayer
Michal Kobecki, Alexey V. Scherbakov, Tetiana L. Linnik +7
Energy harvesting is a modern concept which makes dissipated heat useful by transferring thermal energy to other excitations. Most of the existing principles for energy harvesting…
