The present disclosure provides a liquid crystal phase shifter array, a driving method thereof, and a laser scanner. The liquid crystal phase shifter array includes a plurality of liquid crystal phase shifter units arranged in array, a first substrate and a second substrate disposed opposite to each other, a liquid crystal layer provided between the first substrate and the second substrate, a first electrode provided on the first substrate, and a second electrode provided on the second substrate. Each liquid crystal phase shifter unit includes a first optical waveguide provided on a side of the first substrate proximal to the liquid crystal layer and arranged to be in direct contact with the liquid crystal layer.

Liquid crystal phase shifter array, driving method thereof, and laser scanner

A liquid crystal phase shifter, a method for producing the same and a method for shifting phase of electromagnetic wave are provided. The liquid crystal phase shifter includes: a first base substrate and a second base substrate opposed to each other; a first liquid crystal modulation portion and a second liquid crystal modulation portion between the first base substrate and the second base substrate; a first electromagnetic wave transport layer between the first base substrate and the first liquid crystal modulation portion; and a second electromagnetic wave transport layer between the first base substrate and the second liquid crystal modulation portion. The first liquid crystal modulation portion is configured to modulate a phase of electromagnetic waves in a first frequency range and the second liquid crystal modulation portion is configured to modulate a phase of electromagnetic waves in a second frequency range different from the first frequency range.
