Abstract

We present measurements at 10.6 µm that demonstrate electronic tuning of the polarization response of asymmetric-spiral infrared antennas connected to Ni–NiO–Ni diodes. Continuous variation of the bias voltage applied to the diode results in a rotation of the principal axis of the polarization ellipse of the spiral antenna. A 90° tuning range is measured for a bias voltage that varies from -160 to +160 mV .This effect is caused by a small asymmetry of the deposited diode contact or by a variation of the detector capacitance with the applied bias voltage.
