Quantum Theory of Loss-Induced Transparency in Coupled Waveguides

Increasing loss in one waveguide can counterintuitively enhance light transmission. Using the Heisenberg-Langevin formalism, we show that this loss-induced transparency effect extends to single-photon states, for both separable and entangled cases.

Abstract

Increasing loss in one waveguide can counterintuitively enhance light transmission. Using the Heisenberg-Langevin formalism, we show that this loss-induced transparency effect extends to single-photon states, for both separable and entangled cases.
