Abstract

We have developed a quantum theory of the action of attenuating and amplifying four-port devices starting from the canonical quantization of the electromagnetic field in arbitrary linear, causal dielectrics. In particular, we have presented formulas for calculating the quantum state of the outgoing fields from the quantum state of the incoming fields and the device for given complex refractive-index profile without placing frequency restrictions.
