We report broadband monolithic transmitters and receivers IC's for mm-wave electromagnetic measurements. The IC's use nonlinear transmission lines (NLTL) and sampling circuits as picosecond pulse generators and detectors. The pulses are radiated and received by planar monolithic bow-tie antennas, collimated with silicon substrate lenses and off-axis parabolic reflectors. Through Fourier transformation of the received pulse, 30-250 GHz free space gain-frequency measurements are demonstrated with an accuracy approximately = 0.17 dB, RMS.read more

TL;DR: In this paper, a coupled oscillator model is used to predict the limiting speed of response and generation efficiency of different electrooptic materials, including lithium tantalate, when the duration of the exciting femto second optical pulse is comparable to the period of lattice vibrations.

Efficient generation of 380 fs pulses of THz radiation by ultrafast laser pulse excitation of a biased metal‐semiconductor interface
TL;DR: In this paper, the authors demonstrated a new method of generating pulses of freely propagating THz electromagnetic radiation, which are the shortest directly measured THz pulses in free space to date and are more powerful than those generated by Hertzian dipoles or by resonant dipole antennas.

TL;DR: In this paper, the radiation pattern of a bow-tie antenna of finite length and infinitesimal thickness, placed on a lossless dielectric substrate, is analyzed based on a representation of the current density on the metal surface of the antenna as a sum of an imposed quasistatic term and a set of current modes with unknown amplitudes.
