This paper employs the extended trial equation method to retrieve chirped optical soli ton solutions to Chen-Lee-Liu model that describes pulse propagation through optical fibers. Bright and singular optical soliton solutions are recovered by the application of this algorithm. As a byproduct, singular periodic solutions fall out. These soliton solutions are obtained with constraint conditions that are also presented. (C) 2017 Elsevier GmbH. All rights reserved.
