The avalanche delay effect in sine-gated single-photon detector based on InGaAs/InP SPADs
Alexandr Filyaev, Anton Losev, Vladimir Zavodilenko +1
A sine-gated single-photon detector (SPD) intended for use in a quantum key distribution (QKD) system is considered in this paper. An "avalanche delay" effect in the sine-gated SPD…
Investigation of the Effects of the Multiplication Area Shape on the Operational Parameters of InGaAs/InAlAs SPADs
Anton Losev, Alexandr Filyaev, Vladimir Zavodilenko +2
A 2D model of an InGaAs/InAlAs single photon avalanche photodiode has been developed. The influence of the active area structure in the multiplication region on the diode's operati…
Automated verification of countermeasure against detector-control attack in quantum key distribution
Polina Acheva, Konstantin Zaitsev, Vladimir Zavodilenko +3
Attacks that control single-photon detectors in quantum key distribution using tailored bright illumination are capable of eavesdropping the secret key. Here we report an automated…
Investigation of the dependence of noise characteristics of SPAD on the gate parameters in sine-wave gated single-photon detectors
A. V. Losev, V. V. Zavodilenko, A. A. Koziy +2
In this paper, we have investigated a self-developed sine wave gated (SWG) single-photon detector (SPD) for 1550 nm wavelength primary for quantum key distribution (QKD) usage. We…
Investigating the coherent state detection probability of InGaAs/InP SPAD-based single-photon detectors
Andrey Koziy, Andrey Tayduganov, Anton Losev +3
In this work we investigate the probabilities of detecting single- and multi-photon coherent states on InGaAs/InP sine-gated and free-run single-photon avalanche diodes. As a resul…
Dead time duration and active reset influence on the afterpulse probability of InGaAs/InP single-photon avalanche diodes
A. V. Losev, V. V. Zavodilenko, A. A. Koziy +4
We have performed a detailed study of the dependence of afterpulse probability in InGaAs/InP sine-gated SPAD on the dead time and the existing approach for its implementation. We d…
Direct phase modulation via optical injection: theoretical study
Roman Shakhovoy, Marius Puplauskis, Violetta Sharoglazova +4
Direct phase modulation via optical injection is a newly developed method for coding the phase of a gain-switched laser, which meets high requirements placed on transmitters for qu…
