Photonic waveguiding structures with loss and gain
Original language description
Passive real-world waveguiding structures are inevitably lossy, and some of them, such as plasmonic waveguides, exhibit even very strong attenuation. Losses can be compensated by including active components with gain. In this paper we discuss propertiesof waveguiding structures with generally complex dielectric permittivity distributed across their cross-section. In particular, we focus on the existence of modes that exhibit balance between loss and gain and that can propagate unattenuated provided thesuitable conditions are satisfied. Specifically, we examine power transmission in the structures with a balance of loss and gain supporting lossless propagation of two modes. We demonstrate that when both modes are excited simultaneously, the total transmitted power is not conserved as the modes propagate along the waveguide. We also show that even if one of the modes propagates with gain, the maximum attainable transmitted power is strongly influenced by back-reflections from the inter
