Abstract
A microwave circuit includes at least one inductive portion and at least one capacitive portion and having a resonance frequency, the microwave circuit including a material which acts as a dielectric for the capacitive portion, characterized in that the material acting as a dielectric includes an active region that is an electrically pumped semiconductor heterostructure having at least two energy levels whose energy separation is close to the resonance frequency of the microwave circuit.
