The purpose of these guidelines are to provide style guides for the submission of manuscripts to be published in Current Optics and Photonics (hereinafter referred to as COPP) published by the Optical Society of Korea (hereinafter referred to as OSK).

Manuscripts should be written in English.

1. 1. Manuscripts should be prepared in Microsoft Word format.
2. 2. Manuscripts should be prepared in the following order: title, authors’ names, affiliations & addresses, abstract, keywords, OCIS codes, main text, appendices, acknowledgments, and references.

The title should be concise but sufficiently informative.

1. 1. Authors should be listed in order of the nature and extent of their contribution.
2. 2. If authors have more than one affiliation, numbers should be added in superscript in the upper right corner of the authors’ names and the corresponding numbers should be added in superscript in the upper left corner of the affiliations.
3. 3. The corresponding author should be denoted by superscript “*”, and his/her e-mail address should be provided.

The abstract is an explicit summary, including the problems, methods, main results, and conclusions discussed in the article, and its length should be limited to approximately 200 words or less.

1. Up to 5 keywords can be chosen.
2. Up to 5 OCIS codes can be chosen.

The main text generally consists of multiple sections such as introduction, method, result, discussion, and conclusion. The section titles and organization, however, may be determined with variations for authors to present the work clearly.

1. 1. Figures and tables should be located in the text, and each of them should be called out or referred to in the text. They should be numbered sequentially.
2. 2. Figures and tables should be set as one-column wide (maximum width: 84 mm) if possible. Otherwise, they can be set as two-column wide (maximum width: 180 mm).
3. 3. Figures are printed in black and white by default. Inclusion of figures printed in color incurs additional publication processing charges, which should be paid by authors.
4. 4. In order to include the figures (including graphs, images, photographs, etc.) that are protected by third party copyright, authors should obtain the written permission of the owner of the copyright, which should be properly mentioned in the text.

1. 1. All equations should be created in Microsoft Word Equation Editor or MathType.
2. 2. Equations should be set as one column wide (the maximum width: 85 mm) if possible. Otherwise, they can be set as two-column wide (the maximum width: 180 mm).
3. 3. Units and their denotations should be made in accordance with international practices.

Appendices and acknowledgments can be added after the main text if necessary.

References should be objectively verifiable. They should be cited in the format of [1, 2] or [3-6] in the main text, and should be listed collectively after the main text in the ways exemplified in the following:
