Author Style Guide & Templates
When preparing the manuscripts, the authors should follow the style guide and template of Chinese Optics Letters. Adherence to COL style guide is essential for efficient review and publication of submissions. Additional information and template for MS Word & WordPerfect and LaTeX & REVTeX are also available. See the Authors tab for general information for authors.

1. Title
The title should be concise but informative. Avoid beginning with an article or a preposition. The words "new" or "novel" should be avoided in the title and the text for legal reasons. Titles may be edited by the publisher to facilitate computer search.

2. Author names and Affiliations
Author names should be given in full and consistent form to facilitate indexing. Affiliations and postal addresses for all authors should appear on the title page.

3. Abstract
The abstract should be no longer than 100 words. It should be informative, without descriptive words or citations, and contain the major conclusions and quantitative results or other significant items in the paper. Together with the title, the abstract must be adequate as an index to all the subjects treated in the paper, and will be used as a base for indexing.

4. Equations
Equations should be punctuated and aligned to bring out their structure, and numbered consecutively in round brackets on the right-hand side of the page.
Notation. Notation must be legible, clear, compact, and consistent with standard usage. In general, acronyms should be defined at first use.
Variables and Vectors. Set single-letter variables in italics (Eg. M). Set vectors in boldface (Eg. m). Functions, derivative "d," abbreviations, and multi-letter identifiers should be set in roman (plain) type (Eg. α, cos, ∫...dx).
Fences. For simple bracketing the usual order of parentheses and brackets is { [ ( { [ ( ) ] } ) ] }.
Bit and Byte. The standard abbreviations for bit and byte are b and B, respectively. To avoid confusion, these units should be spelled out in most cases (1 bit, 20 GB). Display equations should be broken and aligned for two-column display unless spanning across two columns is essential. Equations should be centered with equation numbers set flush right. For Math Type math, use the Format Equations feature to format all equations as Times + Symbol 10. Note: There must be a blank line space above and below each displayed equation.

5. References
References should be numbered consecutively in the order in which they are first referenced in the body of the manuscript. Two references [2,3] should be included together, separated by a comma, and three or more consecutive references should be indicated by the bounding numbers and an en dash [1-4]. When compiling your references, be sure to include the titles of articles. COL requires this information before a paper can be sent to peer review. All reference authors should be included in the reference list but when reference authors are mentioned in the text, use surnames only (unless further clarity is needed), and use "et al." and first author name when three or more authors are given. The format of references is as follows:

6. Figures and Tables

Figures should be suitable (resolution above 300 dpi) for immediate reproduction and embedded in the text. They should be set as one column wide (6-8 cm) if possible unless two-column display is essential. In the figures, the main lines should be about 0.3 mm in width, and the assistant lines 0.15 mm. Notations in the figures should be distinct and consistent with the same ones in the text, and their font size will be 7-9 pt. Figures should also be uploaded as separate figure files. Each figure should have its own caption. Color Art is Online Only, and free to authors.

Tables must be numbered in order of appearance and identified with appropriate titles. The table title, which should be brief, goes above the table. Note that tables are usually typeset, not scanned (tables cannot be electronically reduced in size). Tables should be set in one column wide if possible and be placed near their first mention in the body.

7. Funding Sources
Please identify all appropriate funding sources by name and contract number in the Acknowledgment section.

8. Article Length and Proof
Note that Chinese Optics Letters has a limit of five printed pages. If a paper exceeds this limit, it must be shortened before the paper is accepted. If the page proof is over the five-page limit, the proof must be shortened before the paper can be assigned to a final issue. Authors should use the COL Word or LaTeX templates to prepare manuscripts to facilitate length checking. Authors will receive page proofs of their papers. Corrected proofs should be returned to the COL Editorial office as soon as possible, to avoid publication delays.

9. Copyright
As the manuscript has been accepted, all authors should transfer the copyright of the article, including that of the printing and on-line version, to the publisher. All authors must sign the Transfer of Copyright Agreement before the article can be published. This transfer will ensure the widest possible dissemination of information.

Peer review process

  1. First Review
    Manuscripts are screened by the editorial office regarding the manuscript format and the duplication rate. Manuscripts are then preliminarily evaluated by the editors-in-chief and editorial board members to ensure they meet the journal's rigorous scientific standards and are eligible for peer review. The manuscript might be unsubmitted or rejected in this step.
    This step averages 1-2 weeks and may extend under special occasions.
  2. Peer Review
    Manuscripts that meet these criteria are single-blind reviewed by at least two referees. The referees provide detailed comments and recommendations to help the editorial board members arrive at the appropriate editorial decision.
    This step averages 30 days and may extend under special occasions.
  3. Author Revision
    Authors should carefully address all reviewer comments when submitting a revised manuscript.
    The revision time is 7/10 days, and may extend under special occasions.
  4. Re-review
    Revised manuscripts are evaluated by the editorial board members and may be sent to the original or new referees.

  5. Appeal
    Authors may appeal to the editorial office to reconsider a rejection decision if they believe that the reviewers have seriously misjudged the manuscript. All appeals will be given careful consideration. The editorial board members and/or editors-in-chief will determine if further consideration is merited or if the original decision should stand.
    *Submissions from members of the editorial board are handled by an editorial board member who is not connected with the manuscript to ensure that such submissions receive an objective and unbiased evaluation.
