Abstract :
We report fabrication of THz fiber Bragg gratings (TFBG) using CO2 laser inscription on subwavelength step-index polymer fibers. A TFBG with 48 periods shows a ~4 GHz-wide stop band and ~15 dB transmission loss. The simulated and experimental results demonstrate potential of such gratings in paper thickness monitoring, with experimental spectral sensitivities of ~ -0.67 GHz / 10 μm.
