Abstract:
A silicon-based photoconductive microwave switch has
been designed and fabricated within a coplanar waveguide on a high
resistivity Si substrate. This device offers improved signal attenuation
per incident optical power when compared with other types of optically
controlled attenuators that have been reported. Attenuation of more than 30 dB was achieved by illumination from a single infrared LED.
