In one embodiment, an image guide coupler switch is provided having a dielectric image guide coupler with a coupling control circuit. In this embodiment the coupling control circuit has at least one field pick up probe which extends at least part way across the image guide coupler. A switch is connected in series with the at least one field pick up probe. An optional capacitor my be provided in series with the series with the switch. In some embodiments, a pair of field pick up probes is provided, with the switch being connected in series with and between the pair of field pick up probes. Some embodiments may have multiple pairs of field pick up probes, each having a switch connected in series with a pair of field pick up probes. An optional capacitor may be provided in series with the pair of field pick up probes.
