Broadband THz Generation from Photoconductive Antenna
Since the observation of radiation in the Terahertz (THz) frequency range from photoconductive antennas exited by femtosecond (fs) laser pulses, considerable efforts have been made to understand the mechanism responsible for THz generation, and to develop applications in THz Time-Domain Spectroscopy (THz-TDS). In this paper, the calculation of THz radiation from biased photoconductive antenna i...
متن کاملThree-Contact Photoconductive Antenna for Polarization Detection of THz Radiation
For polarization measurement of terahertz (THz) electromagnetic radiation we conventionally have been using a set of wire-grid polarizers. In the THz time domain spectroscopy (TDS) measurements, such a method requires twice of the time-delay scans, which is time consuming and can be the origin of the systematic error caused by the intensity fluctuation of laser. In addition, the efficiency of a...
متن کاملDemonstration of a High-Efficiency Reflectarray Antenna at 1 THz Based on Dielectric Resonators
A reflectarray antenna composed of more than 87000 single-crystal silicon resonators on a gold ground plane is experimentally demonstrated to achieve efficient beam focusing at 1 THz. The functionality of the reflectarray as a collimator is also verified by the principle of antenna reciprocity. Because of the low-loss and nondispersive nature of high-resistivity silicon in the submillimeter reg...
متن کاملAntenna Enhanced Graphene THz Emitter and Detector.
Recent intense electrical and optical studies of graphene have pushed the material to the forefront of optoelectronic research. Of particular interest is the few terahertz (THz) frequency regime where efficient light sources and highly sensitive detectors are very challenging to make. Here we present THz sources and detectors made with graphene field effect transistors (GFETs) enhanced by a dou...
متن کاملOptical recoil of asymmetric nano-optical antenna.
We propose nano-optical antennas with asymmetric radiation patterns as light-driven mechanical recoil force generators. Directional antennas are found to generate recoil force efficiently when driven in the spectral proximity of their resonances. It is also shown that the recoil force is equivalent to the Poynting vector integrated over a closed sphere containing the antenna structures.
