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.
