Meanings
-
(uncountable) The act of coupling two tuned transformers so as to create a broader bandwidth.
We observe continuous transition of the coupling between the fiber-taper waveguide and the microresonator from undercoupling to critical coupling and then to overcoupling regimes by increasing the pump power even though the spatial distance between the resonator and the waveguide was kept fixed.
