An integrated broadband bowtie antenna for THz detection with a double quantum well

The purpose of this paper is to show how an antenna can be integrated with a double quantum well device to enhance the detection of THz radiation. The principle of operation of the detector is first explained and the fabrication technique is outlined. The detector has the advantage of having narrow band response and electrically tunable over a wide range of THz frequencies. A bowtie antenna is integrated with the double quantum well (DQW) detector to couple THz radiation to the device because of its wide bandwidth. This detector has many applications, ranging from chemical and biological agents detection to astrophysical applications. Simulation results of the antenna obtained to this point are presented.
