AbstractThis letter focuses on the fabrication and characterization of a terahertz detector integrated with a group of low pass filters and resonant antennas. The detector operates as a self-mixer on GaN/AlGaN high electron mobility transistor(HEMT). At room temperature, a strong dc photocurrent is produced with the aid of the antennas and filters. The responsivity of our HEMT device is estimated to be53 mA/W and a noise equivalent power of1 nW/ Hz can be achieved at300 K. In addition, the sensor properties of a similar HEMT detector without filter are tested as a comparison.?2011 American Institute of Physics.
