Comparison of confinement and loss of plasmonic waveguides [PDF]
IEEE Photonics Conference 2012, 2012 We have compared a number of well known plasmonic guides in terms of power confinement, normalized power density, and propagation loss. We have identified the relative advantages and limitations of these guides.

Numerical Investigation of Confinement Losses in Semiconductor-core Optical Fibers [PDF]
2021 IEEE Research and Applications of Photonics in Defense Conference (RAPID), 2021 The sources of the confinement losses in semiconductor-core optical fibers are numerically investigated by introducing fabrication-inspired imperfections such as micro-cracks and core ellipticity. The imperfections increase the losses up to 200 dB/m at the targeted spectrum that is comparable to experimental findings.
