A cross-shaped infrared polarized light bridge based on a photonic crystal waveguide. The present invention aims to provide a polarized light bridge that is small in structural size, high in polarization degree, convenient to integrate, and highly efficient, besides which, crosstalk is not caused at a cross intersection. The cross-shaped infrared polarized light bridge comprises a photonic crystal waveguide provided with a complete bandgap. The photonic crystal waveguide is in a cross shape. Waveguide defect dielectric columns are disposed in the photonic crystal cross-shaped waveguide. The waveguide defect dielectric columns are square defect dielectric columns (6) and round defect dielectric columns (7). The photonic crystal cross-shaped waveguide comprises a vertical TE waveguide, a horizontal TM waveguide, a TM optical signal input port (1), a TM output port (3), a TE optical signal input port (2), and a TE output port (4). The two input ports (1,2) of the photonic crystal waveguide separately input a TM optical signal and a TE optical signal. Mutual influence is not caused at a cross intersection position of light circuits formed by the TM wave and the TE wave in a shared central area. The input TM optical signal is output from the TM output port (3). The input TE optical signal is output from the TE output port (4).
