1 | An injection- switchable erbium-doped fiber laser (EDFL) with two output ports based on a ring structure is proposed. | |
2 | The results of this thesis are very important to the design and the applications of erbium-doped fiber amplifiers. | |
3 | A concise theory of waveguide is first reviewed in this paper, and the amplification theory of er-doped glass waveguide is introduced. | |
4 | It is found that there are intense radiation trapping and concentration quenching effect in erbium-doped tellurite glasses. | |
5 | One advance that exploits quantum confinement makes use of rare earth elements, such as erbium, that scientists know to be good light emitters. |
