Optical-pumping attack on a quantum key distribution laser source
Maxim Fadeev, Anastasiya Ponosova, Qingquan Peng +3
We report a new type of vulnerability in practical implementations of quantum key distribution systems. We show that it is possible to increase the pulse energy of a source laser d…

Influence of optical self-injection on statistical properties of laser-pulse interference
Roman Shakhovoy, Elizaveta Maksimova, Matvey Boltanskiy +1
Pulsed optical self-injection markedly affects the emission characteristics of semiconductor lasers. In this work, we analyze its influence on the statistical properties of laser-p…
