We demonstrated a new type of grating polarizing beam-splitter (GPBS), which is made of an oriented thin film of polydiacetylene (PDA) and has the advantages of light weight and easy fabrication. The extinction ratios of the 2.5-µm-thick element were -8.7 dB and -7.4 dB for the 0th-order and the 1st-order diffraction beams, respectively. The problems that must be solved prior to practical use are discussed.
