We demonstrate a ball-lens based optical interface for coupling between a single mode fiber
and a silicon grating coupler from the back side of a photonic integrated circuit (PIC). This …

A novel configuration of photonic sensors based on a single-channel bimodal interferometer
is proposed. The design consists of a subwavelength grating (SWG) periodic structure …

A proper antibody immobilization on a biosensor is a crucial step in order to obtain a high
sensitivity to be able to detect low target analyte concentrations. In this paper, we present an …

In this paper we analyze the performance of a refractive index sensor based on resonant
optical structures obtained by closing on itself waveguide Bragg gratings. In particular, a …

[EN] In this letter, we present experimental results of antibody detection using a biosensor
based on photonic bandgap structures, which are interrogated using a power-based readout …

A photonics integrated system is disclosed, comprising a substrate, an integrated
interferometer integrated in the substrate and being configured for receiving radiation from a …

“Photonics” is the field of science that involves the manipulation of light, ie photons. A photon
is the smallest quantity (quantum) of electromagnetic radiation and has neither mass nor …
