Bragg filters stand as a key building blocks of the silicon-on-insulator (SOI) photonics platform, allowing the implementation of advanced on-chip signal manipulation. However, achieving narrowband Bragg filters with large rejection levels is often hindered by fabrication constraints and imperfections. Here, we present a new generation of...

Bragg filters stand as a key building blocks of the silicon-oninsulator photonics platform. However, achieving narrowband Bragg filters with large rejection is challenging due to fabrication constraints and imperfections. Here, we present our recent results in de development highperformance Bragg filters based on subwavelength and modal...

— Periodically patterning Si with a pitch small enough to suppress diffraction, we synthesize an effective photonic medium with refractive index between those of Si and the cladding material. This technique releases new degrees of freedom in engineering of light-matter interaction, chromatic dispersion and light propagation in Si photonic...

We will discuss a novel entangled photon pair source based on an on-chip silicon ring resonator, enabling the distribution of wavelength multiplexed quantum information in standard telecommunication channels. This source opens the route towards out-of-the laboratory quantum cryptography systems showing augmented bit rates.
