Automatic configuration of programmable photonic digital circuits based on genetic algorithms

Abstract

Programmable photonic circuits, a good way to provide enough function flexibility for photonic circuits, have great potential to be realizing multi-function. However, it has been a challenge to configure a huge mesh network in order to achieve the target function. In this paper, a path selection method based on genetic algorithms has been introduced to complete the automated setting of the huge mesh network. pSim, the most advanced simulation tool of integrated circuits, is used for verification of the performance of automatically selecting the optical path on the square mesh network. Moreover, an optoelectronic hybrid circuit, which can implement state transition, based on this algorithm is proposed.
