| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Behavior of terahertz pulse propagation in hollow optical fibers is investigated by using terahertz time-domain spectroscopy. From evaluation of transmission loss spectra of hollow optical fiber, it was found that, in addition to TE11 mode that is the lowest order mode in terahertz metal-hollow fiber, TM11 mode propagates as well. Short-time Fourier transform is also applied for investigation of mode properties and as a result, it is confirmed that the interference peaks in the loss spectra are due to mode mixing in hollow optical fibers. Finally dispersion properties are derived from phases of transmitted pulses and it is found that group velocities in hollow optical fibers decrease in low frequency region. | |
