Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Optical phased arrays are a powerful tool for the compact implementation of beam scanners. Tuning of large-scale 2D arrays is, however, a daunting challenge that requires the integration of a very large number of phase tuners, resulting in challenging integration and power management. We combine 1D beam steering in two directions with nonlinear mixing of the generated beams by means of an optically addressable liquid crystal cell integrated on top.Addressable angular ranges and optimization of the nonlinear transformation strength are investigated.
