Fiber-Optic Switch Based on Fiber Bragg Gratings

This letter presents a design proposal of optical packet switch architecture which incorporates fiber Bragg gratings (FBGs) and fiber delay line (FDL) to resolve contention among packets. The main feature of the architecture is the efficient use of FBG to create the buffer and there is no requirement of demux and splitter inside the buffer as in most of the conventional optical packet switch (OPS) architectures. Thus, the buffer is simplified in terms of required number of components used to create buffer. The FBG inside the buffer is a new approach towards buffering structure. Finally, comparative study of the proposed architecture with other architectures is presented.
