In this Letter, we design and experimentally demonstrate the first, to the best of our knowledge, integrated optical-phased-array-based (OPA-based) system that simultaneously emits and controls beams of red, green, and blue light. First, we develop this visible-spectrum-spanning integrated OPA-based system architecture and the corresponding requisite devices and fabricate the system in a 300-mm wafer-scale silicon-photonics foundry process. Next, we use the integrated OPA-based system to experimentally demonstrate simultaneous 2D beam steering at red, green, and blue wavelengths. Finally, we apply the integrated OPA-based system to display a 2D RGB image of the MIT logo. This work enables visible-spectrum-spanning functionality for emerging applications of integrated OPAs that require visible-light operation, such as displays, 3D printing, atomic quantum systems, underwater optical communications, and optogenetics.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
