Journal ArticleDOI
A New Paradigm in High-Speed and High-Efficiency Silicon Photodiodes for Communication—Part I: Enhancing Photon–Material Interactions via Low-Dimensional Structures
Hilal Cansizoglu,Ekaterina Ponizovskaya Devine,Yang Gao,Soroush Ghandiparsi,Toshishige Yamada,Aly F. Elrefaie,Shih-Yuan Wang,M. Saif Islam +7 more
TL;DR: In this article, the authors present the recent efforts in enhancing the photon-material interactions by using low-dimensional structures that can control light for more interaction with the photoabsorbing materials, slow down the propagation group velocity and reduce surface reflection.
Journal ArticleDOI
