Abstract :
We have build THz multilayer mirrors based on fabricated z-cut quartz wafers of 25 mm diameter. Using THz time-domain spectroscopy initial measurements show that the mirror reflectivity can be tuned at least up to 98.6%. We also observed cavity modes in a THz cavity made from such mirrors.
