FAR-SITE – Far-field silicon photonics sensors

Based on our extensive experience in grating design, in this project we aim to demonstrate silicon photonic sensors that can interact with their macroscopic environment, at centimeter-scale distances, without using any bulk-optics systems. Specifically we aim to develop advanced grating couplers capable of radiating Gaussian beams with beam waists larger than 100 micrometres. Using these gratings we will demonstrate an on-chip vibrometer with lens-less operation and centimetre scale working distances.
