We present an erratum to our paper [Opt. Express2631617 (2018)10.1364/OE.26.031617OPEXFF1094-4087]. Due to the statistical requirements of the postdoctoral outbound assessment, the first organization of the research articles must be "Nanjing University". As all our experimental data in this article is done in the laboratory of Nanjing University, so "Nanjing University" should be used as the first organization to meet the appraisal requirements of the postdoctoral workstation.
