本发明提供一种图案化偏振转换器，其具有能够用于将输入的线偏振光转换成具有空间变化偏振状态的输出光的多个区，其中包括基于区的图案产生线偏振光的区和产生圆偏振光的区。具有多个区的图案化偏振转换器可以用在偏振传感器应用中，以检测输入光的偏振状态。本发明还提供了图案化径向和方位角偏振转换器，其用于诸如光钳的应用中，另外，图案化偏振转换器可以用于制造具有相同图案的更多图案化偏振转换器，其中使用单步光配向将已有图案化偏振转换器的图案复制到未图案化的光配向层。The present invention provides a patterned polarization converter having multiple domains that can be used to convert input linear polarized light to output light with spatially varying polarization states, including domains that produce linearly polarized light and domains that produce circular polarized light based on the patterning of the domains. A patterned polarization converter having multiple domains may be used in a polarization sensor application capable of detecting the polarization state of input light. The present invention further provides patterned radial and azimuthal polarization converters, which have utility in applications such as optical tweezers. Additionally, patterned polarization converters may be used to fabricate more patterned polarization converters having the same pattern using one-step photoalignment to copy the pattern of an existing patterned polarization converter to an unpatterned photoalignment layer.
