Abstract: Linear polarizers with high extinction ratios (ERs) and low insertion losses (ILs) are essential for terahertz applications. We fabricated a Ti 3 C 2 T x MXene-based terahertz linear polarizer using femtosecond pulse laser ablation. A 7-µm vacant linewidth was drawn on a drop-cast Ti 3 C 2 T x MXene thin film. Increasing the line density improved the ER (from 11 dB to 20 dB) and reduced the IL (from 1.5 dB to 0.3 dB). The polarizer’s transmittance follows Malus’s law, with directivity surpassing that of PEC-based counterparts. This outstanding performance is attributed to Ti 3 C 2 T x MXene’s high conductivity and large absorption, making it a cost-effective linear terahertz polarizer.
