Abstract

In order to transfer a range of important optical experiments into the microwave regime, a pair of near-identical, weakly coupled resonators is required. We describe a simple tuning mechanism for taking a pair of coupled, coplanar resonators through the avoided crossing in a controlled way. We see no obvious degradation of their high quality factor and find very good agreement with theoretical expectations.
