We simulate the impact of interference visibility on system performance and measure the visibility of a pair of interferometers as a function of their relative time delay and intensity imbalance. In addition, our analysis highlights the effect of laser chirp on system performance.</p> Dewey 500.2 European Commission Quantum-Safe-Internet 101072637 QSI EU HE 35 Groupe de physique appliquée 135 false 1404 Groupe Thew Applied physics letters 127 4 bfce8e98-1767-4b29-8fab-fb7834015b78 Article (Published version) Restricted 044001_1_5.02802321.pdf 1517027 application/pdf ee0022e5917685e82129cb1aa8c21c6fa4d8d95c1feb466b55d5172a90460b39 restrictedAccess Faculté des sciences / Section de physique / Groupe de physique appliquée
