This paper obtains dark and singular optical solitons from Kundu-Eckhaus model. There are two integration algorithms that are adopted. These are extended trial equation method and the extended G'/G-expansion scheme. Constraint conditions guarantees existence of these solitons. As a byproduct, singular periodic solutions and plane wave solutions fall out. (C) 2016 Elsevier GmbH. All rights reserved.
