ABSTRACT
We report the observation of the well defined oscillation of a picosecond tetrahertz (ps THz) pulse within a dielectric concentric cylindrical cavity, which is coupled to an incoming focused beam of ps THz pulses by the optical tunneling effect of frustrated total internal reflection. The tunneling barrier is an 18-μm-thick air slab, situated between the plane surfaces of a hyperhemicylindrical focusing lens and the cavity. The output of the quasioptic cavity consists of a train of ps THz pulses with a frequency spectrum from 0.1 to 1.0 THz. Good agreement between experiment and theory is obtained in both the time and frequency domains. © 2001 American Institute of Physics.
