  • Abstract
    A novel optoelectronic switching array is proposed and a trial switch of the type used at the array crosspoints is characterised. Isolation in excess of 50 dB can be obtained over a frequency range from 30 Hz to 100 MHz with appropriate biasing. The use of optoelectronic crosspoint switch arrays for f.d.m.t.v. signal switching appears to be possible.
