Transient response of planar integrated optoelectronic antennas

Abstract

Broadband tapered slot antennas monolithically integrated on ion damaged silicon-on-sapphire substrates are driven by picosecond photoconductivity to generate and detect millimeter waves. The time-dependent electromagnetic impulse response of these transceivers is modeled by relating the antenna structure and the shape of the exciting pulse. The far-field response is observed to consist of a traveling-wave component and a standing-wave component, which is also predicted by the model.
