Abstract: Strongly-driven nonlinear optical processes such as spontaneous parametric down-conversion and spontaneous four-wave mixing can produce multiphoton nonclassical beams of light which have applications in quantum information processing and sensing. In contrast to the low-gain regime, new physical effects arise in a high-gain regime due to the interactions between the nonclassical light and the strong pump driving the nonlinear process. Here, we describe and experimentally observe a gain-dependent group delay between the multiphoton pulses generated in a high-gain type-II spontaneous parametric down-conversion source. Since the group delay introduces distinguishability between the generated photons, it will be important to compensate for it when designing quantum interference devices in which strong optical nonlinearities are required. Joint work with Guillaume Thekkadath, Martin Houde, Duncan England and Ben Sussman.

English below Les branches étudiantes IEEE de l'INRS et de Polytechnique vous invitent à participer au concours de design "Rectenna". Les étudiants devront concevoir une rectenna en fonction du cahier des charges fourni par les organisateurs. La fréquence, la diode, le niveau de puissance d'entrée ainsi que d'autres paramètres seront communiqués aux étudiants inscrits 2 semaines avant le concours. Durant cette période, les concurrents concevront leur rectenna avec le logiciel souhaité. Le jour du concours, les étudiants construiront leurs prototypes à l'aide du matériel fourni. Sur la base d'une Figure de Mérite (FoM) qui inclut principalement la taille et la puissance de sortie, les gagnants seront classés et récompensés par une carte cadeau (1ère position : 300$, 2ème position : 200$ et 3ème position : 100$) Nous nous occupons de la nourriture et des rafraîchissements. ----------------------------------------------------------------------------------------------------------------------------------------- The IEEE Student Branches of INRS and Polytechnique invites you to take part in the Rectenna Design Competition. Students will have to design a rectenna based on the specifications provided by the organizers. Frequency, diode, input power level and other parameters will be communicated to the registered students 2 weeks prior the competition. During this period, competitors will design their rectenna with the desired software. The day of the competition, students will build their prototypes using the provided materials. Based on a Figure of Merit (FoM) that mainly includes size and output power, the winners will be ranked and rewarded with a gift cards (1st position : 300$, 2nd position : 200$ and 3rd position : 100$) We take care of food and refreshments. À bientôt!
