A SiN-Si dual-layer optical phased array (OPA) chip is designed and fabricated. It combines
the low loss of SiN with the excellent modulation performance of Si, which improves the …

We demonstrate a 1× 64 optical phased array (OPA) based on a silicon on insulator (SOI)
platform with integrated silicon nitride. The input port of the OPA is fabricated using a silicon …

Light detection and ranging (LiDAR) is widely used in scenarios such as autonomous
driving, imaging, remote sensing surveying, and space communication due to its …

We present a chip-based optical beam scanner based on a dispersive optical phased array
(OPA) that illuminates the far field with a pixelated pattern. To scale up the OPA to a large …

We propose a highly directional waveguide grating antenna for an optical phased array,
achieving high directionality of more than 97% by interleaving the trenches with different …

We propose a 2D scanning optical phased array circuit that reconciliates the requirements of
resolution and range in automotive LiDAR. Using only the wavelength of the laser source to …

Active imaging and structured illumination originated in “bulk” optical systems: free-space
beams controlled with lenses, spatial light modulators, gratings, and mirrors to structure the …

We present a Vernier optical phased array transceiver architecture that suppresses grating
lobes and can extend the field-of-view. The first experimental demonstration shows Vernier …

Integrated optical antennas featuring large effective lengths and high radiation efficiency
(RE) are essential to chip-scale light detection and ranging technology. However, there are …
