Current Optics and Photonics (COPP) publishes papers reporting recent advances, state-of-the-art research and development results in all areas of optical science and technology. COPP is published six times (February, April, June, August, October and December) a year. Original contributions in all technical fields of optics such as optical materials, optical devices, optical systems, and/or topics related to theoretical and experimental aspects of new principles are welcome. The language used in manuscripts should be English. Submission of a manuscript indicates that it has not been published previously and is not concurrently submitted for publication elsewhere. COPP is open accessible at OSA Publishing. COPP inherits the tradition of Journal of the Optical Society of Korea (JOSK) that has been published as one of the official journals of the Optical Society of Korea (OSK) since 1997. The official abbreviated journal title will be Curr. Opt. Photon. and its acronym will be COPP. The official title change from JOSK and corresponding Impact Factor (IF) calculation will be completed after four years (2020). During the first two years (2017~2018), COPP will not have an IF because the journal would not have a history of articles published under the new title for each of the two preceding years. In the third year (2019), separate IFs will be calculated for both JOSK and COPP (or COPP may have an Immediacy Index for the third year in place of the IF). From the fourth year (2020), only COPP will be maintained in JCR with a proper IF. (JOSK changes its title to Current Optics and Photonics COPP) starting in February 2017.) 2015 JOSK IF: 0.827
