More fiber laser wavelength can switch has the fine structure,the coupling wastage,small volume facilitate integration and many other advantages,is WDM and DWDM (DWDM) important light source.It's performance directly determine the optical communication system of quality,and the growing importance,so it is urgent to its further study,improve the performance becomes a necessary tendency.
This paper expounds the double wave of AWG based on optical fiber laser research,taken together,this thesis mainly divided into the following several pars:
1.Expounds the basic principle of the optical fiber laser and basic structure,and introduces several kinds of wavelength can switch erbium laser optical fiber.
2.On the experiment to have in the optical instrument is introduced in detail,including EDFA,optical attenuator,optical couplers,light WDM device,light the light switch,isolation,filter and phase modulator,strength modulator and so on.
3.To optical fiber laser wavelength further research,and expounds several more stable at room temperature wavelength optical fiber laser technology.
4.Based on double wave AWG optical fiber laser experimental design in detail.
