Abstract: We demonstrate flexible terahertz polarizer of two-dimensional materials MXene via femtosecond pulse laser ablation techniques. The femtosecond pulse laser causes the stripe-lines on the 30 μm thick thin-film of Ti3C2Tx MXene-on-polyimide. One type of polarizer is of 2.5 μm stripe-lines at 1 μm interval distance, and another type of polarizer is of 2.7 μm stripe-lines at 1.55 μm interval distance. Both of these polarizers exhibit electric field extinction ratios in excess of 5 dB. Our works manisfest a cost-effective approach to achieve large area terahertz polarisers rapidly.
