In this paper, a microfibre polarizer based on graphene oxide (GO) is proposed and demonstrated. A microfibre was coated with GO using the drop-casting technique. The extinction ratio (ER) has been measured at wideband range of 1310, 1460, 1550 and 1600nm. The highest ER obtained in this experiment was 37.0dB measured at 1480nm wavelength. The result has been achieved with a GO coating thickness of 24m and coating length of 12mm. This work demonstrates a polarizing effect of GO-coated microfibre.
