An optical Ising machine based on multi-core fiber lasers

Abstract

Summary form only given. In this work, an optical Ising machine that is based on multi-core fiber lasers (MCFL), which play the role of slave lasers, is demonstrated. Specifically, we use a 19-core Yb-doped fiber lasers in the experimental setups. The system is very compact with the length of the multi-core fiber is of about few cm, and the fiber diameter is of 120-micron. In general, the number of cores can be scaled up to a very large number, hundreds or even higher. 2 spatial light modulators, SLM1 and SLM2 is proposed for polarization control of the couplings from master to slave lasers, and to control the mutual coupling among slave lasers corresponding to Zeeman term, and mutual coupling term, respectively, in Ising Hamiltonian.
