Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

In the first part of this thesis, we proposed a stable and wavelength-tunable semiconductor optical amplifier SOA-based fiber laser with Sagnac ring configuration. Here, this fiber ring laser is SOA-based with Sagnac loop mirror to achieve single-frequency output and save energy power. In the second part, we proposed a dual reflected structure erbium-doped fiber (EDF) laser in single-longitudinal-mode (SLM) for wavelength-tuning. The dual reflected structure of EDF laser with a linear cavity employing a passive saturated absorber based (SAB) filter and tunable bandpass filter (TBF) for the SLM lasing and wavelength tuning. In the third part, we proposed a using Saganc loop of optical-injected semiconductor laser scheme for stable and continuous wave (CW) wavelength-tuning. It is by using self-injected Fabry-Perot laser diode (FP-LD) with Saganc loop scheme. And to achieve the continuous wavelength tuning, we can adjust the temperature of FP-LD for wavelength shifting in the laser scheme. In the fourth part, we proposed a stable wavelength-tuning laser in single-frequency by optical-injected FP-LD and reflective semiconductor optical amplifier (RSOA) for long fiber distance propagation. Finally, the output power, wavelength tunable range, side-mode suppression ratio (SMSR) and output stability of the four proposed laser configurations have been experimentally demonstrated and discussed.
