    Figures & Tables(4)
    Illustration of the LC depolarizer. Different directions of optic axes are indicated by different gray scales. The inset depicts the LC orientations in the red circle.
    Flow sheet of the exposure process. Images in green rectangles are exposure patterns for each step; images in red rectangles present the accumulated polarization information correspondingly.
    Micrograph of the LC depolarizer, with the arrows indicating the directions of the analyzer and polarizer. Scale bar is 100 μm.
    DOP results at different incident polarization. Blue dots stand for the DOP for ASE source; red dots stand for those of the 1550 nm laser.
