The scattering property of a terahertz fiber Bragg grating is characterized. The grating is written in subwavelength polymer fiber with a length of 160 periods. The measured full width at half maximum of the radiated beam is approximately 4 GHz, which may be extended by increasing the grating length. Such a grating shall be used in a spectrometer for the terahertz range.
