Theoretical background of microring resonator systems and soliton communication

Abstract

Optical network has been recognized as an efficiently network due to the good channel spacing and large bandwidths. However, the search for a new technique remains. Therefore in this book, an interesting technique using the dark soliton to generate new secured communication carriers is proposed [1, 2]. Dark soliton detection is difficult because its amplitude is vanished during the propagation. To date, several papers have investigated the dark soliton behaviors, where one of them has shown a fascinating result in the dark soliton can be converted into bright soliton and finally detected [3–5]. This means that dark soliton behavior can be used as an communication carrier so that it can be retrieved by the dark-bright soliton conversion. Here the dynamic trapping tool array (DTA) generation scheme is proposed, which are generated by using the multiplexed dark soliton pulses by using a pumped laser in a fiber optic system. The high capacity network and the security concept using multi dark soliton is discussed [6–8].
