We proposed inverse-designed nanophotonic waveguide devices which have the desired
optical responses in the wide band of 1450-1650? nm. The proposed devices have an ultra …

Optical phased array has become a potentially critical component for beam scanner
benefiting from its advantages in cost, mass production, integration, stability and scanning …

Calibrating the phase in integrated optical phased arrays (OPAs) is a crucial procedure for
addressing phase errors and achieving the desired beamforming results. In this paper, we …

Optical phased arrays (OPAs) are renowned for their exceptional ability to manipulate and
direct light beams, positioning them as an ideal choice for solid-state light detection and …

We demonstrate two-dimensional beam steering through wavelength control using a one-
dimensional optical phased array (OPA) in which a path difference is built up in each …

Antennas are important components in optical phased arrays. However, their far-field
performance deteriorates when random phase noise is introduced because of fabricating …

We demonstrate high-speed data transmission with beam-steering using an as-fabricated
silica optical phased array (OPA) chip. In this OPA, a constant optical path difference was …
