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 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

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
