摘要：

In this Letter, we present the first, to the best of our knowledge, liquid-crystal-based integrated optical phased arrays (OPAs) that enable visible-light beam forming and steering. A cascaded OPA architecture is developed and experimentally shown to emit a beam in the far field at a 632.8-nm wavelength with a power full width at half maximum of 0.4 degrees x1.6 degrees and 7.2 degrees beam-steering range within +/- 3.4 V. Furthermore, we show the first visible-light integrated-OPA-based free space-optical-communications transmitter and use it to demonstrate the first integrated-OPA-based underwater wireless-optical-communications link. We experimentally demonstrate a 1-Gbps on-off-keying link through water and an electronically-switchable point-to-multipoint link with channel selectivity greater than 19 dB through a water-filled tank.(c) 2023 Optica Publishing Group
