VOLTAGE CONTROL METHOD FOR LIQUID CRYSTAL ON SILICON TWO-DIMENSIONAL ARRAY, AND RELATED DEVICES

摘要

Embodiments of the present invention provide a method for controlling voltages of a liquid crystal on silicon (LCoS) two-dimensional array. The LCoS two-dimensional array includes a plurality of pixel sets, and the plurality of pixel sets include a first pixel set and a second pixel set. The method includes: determining a plurality of bit sequences, where the plurality of bit sequences include a first bit sequence and a second bit sequence; controlling a voltage of the first pixel set by using the first bit sequence; and controlling a voltage of the second pixel set by using the second bit sequence, where the first pixel set and the second pixel set are in different phase cycles in a port direction of the LCoS two-dimensional array, the first pixel set and the second pixel set have a same phase, and duty ratios of the first bit sequence and the second bit sequence are the same. In the method, jitter of a pixel in the liquid crystal on silicon two-dimensional array can be reduced, and synchronization of jitter of different wavelengths at the same time is ensured, so that degradation of an optical signal-to-noise ratio of a link is avoided.
