Current optical communication systems slowly fall behind the data-carrying capacity needs of the modern world. These systems mostly implement single-mode fibers, which is one of the main reasons why such networks are falling behind. To overcome this issue and increase data rate, wavelength-division multiplexing (WDM) and space-division multiplexing (SDM) arise as very appealing solutions. Both of them utilize components such as demultiplexers, multiplexers, amplifiers, single or multimode fibers, etc. While improving the performance of optical communication systems, it is also important to keep them compact or to use fewer components. To serve these needs, we propose a multipurpose device that can carry our mode conversion and wavelength demultiplexing simultaneously. The proposed device is designed on a Silicon-on-Insulator (SOI) platform by using topology optimization (TO) and ensure …
