Multi Channels Ultra-Narrow Linewidth 1550nm Fiber Bragg Grating
Application:
Phase shift fiber grating is mainly used for Lower noise single frequency Ultra-narrow Linewidth Fiber laser of Laser industrial, or for Single Frequency Semiconductor Laser Diode with External feedback realizing ultra-narrow linewidth laser output.
Other area, Phase shift fiber grating mainly is used as demultiplexer in DWDM system,which can be highly influenced by the shift degree, Position and shift points quantity.
Feature:
Ultra-narrow linewidth , Multi channels, Flexible Combination ,Lower Insert Loss , Low Polarization Dependent Loss.
Phase Shift Fiber Grating Description:
Phase Shift Fiber Grating means: through leading in Refractive Index moudulation sudden changes On the optical Fiber Bragg Grating certain place, it generate two FBGs with fixed phase shift sudden changes at this place.
The two FBGs similar choose Fabry-Perot and allow light with resonant wavelength to insert into fiber bragg grating resistance band and to open a narrow linearity refractive window during resistance band.
Technical Parameter:
| 3db Band Width | 0.3nm |
| Shift Point 3db Band Width | ＜50pm |
| Reflectivity | ＞90% |
| Central Wavelength | 1550nm |
