Abstract :

This paper will describe our recent experimental and theoretical efforts on realizing a PT-symmetric dimer in a pair of optically coupled semiconductor lasers. The origin of PT-symmetry in this system will be motivated by starting from the Lang-Kobayashi laser rate equations and showing how they can be reduced to a PT-symmetric model with appropriate approximations. An experimental implementation of the model will be detailed and comparison to theoretical predictions is made. The results show that the coupled laser system can be a versatile model for the study of PT-symmetric quantum mechanics.
