This year marks 50 years that John Sipe has been either a graduate student or a professor in the Department of Physics at the University of Toronto. To celebrate this, there will be a one-day physics symposium on Tuesday February 21st, 2023 at UofT. 

The kick-off meeting of the National Quantum Science and Tecnology Institute will take place in Rome on Thursday, January 26. See you in Rome!

We demonstrate a programmable silicon nano-photonic chip generating frequency-bin entangled photons. Our device allows dense integration, while ensuring high brightness, fidelity, and purity. These results are now available in Nat. Comm. 

We study the main issues preventing the efficient excitation of guided Bloch surface waves using grating couplers, and we present some solutions to increase the coupling efficiency. These results are now available in J. Opt. Soc. Am. B. 

We demonstrate undetected-photon-based imaging using light generated via stimulated four-wave mixing within highly nonlinear silicon fiber waveguides. This work is now avialable in Photonics Research.

Yesterday, our group went to Stradella to support Luca and his basketball team! A great evening, plenty of sport and fun!

We demonstrate an integrated source of frequency-entangled photon pairs on a silicon photonics chip. The emitter has a coincidence-to-accidental ratio exceeding one thousand. This work is now available in Optics Letters.

We used a Mach–Zehnder interferometer to linearly uncouple two resonators and, at the same time, to obtain their efficient nonlinear coupling. This allows for a controllable generation of photon pairs via SFWM. Check this out in Appl. Phys. Lett. 

The European Union (EU) and Canada annouces the jointly supported research project HYPERSPACE in quantum technology. Our group, along with other colleagues at UniPV, will be part of the research team.

Here we show that single-photon nonlinearities in photonic devices could be achieved in a triply resonant integrated photonic device made of two coupled ring resonators. This results is now available in Optics Letters 

Welcome to Milica Banic, phd candidate of the University of Toronto. Until the end of this year, she will be working in our group as visiting student on approaches for the generation of multipartite state integrated devices . 

Welcome to Prof. John E. Sipe from the University of Toronto. He will be working in our group as visiting professor until the end of this year. He will also teach a mini-course on "Interpretations of Quantum Mechanics".
