Is cineál gríl díraonta iad FBGanna 1270nm go 1610nm nó 1550nm Snáithín Bragg Grating a fhoirmítear trí innéacs athraonta croí an tsnáithín a mhodhnú go tréimhsiúil trí mhodh áirithe. Is gléas éighníomhach scagaire é. Úsáidtear snáithíní grating go forleathan i réimsí cumarsáide snáithíní optúla, braite snáithíní optúla agus próiseáil comhartha snáithíní optúla mar gheall ar a mbeagmhéid, caillteanas comhleá íseal, comhoiriúnacht iomlán le snáithíní optúla agus ábhair chliste leabaithe, agus tá a dtonnfhad athshondach íogair do na hathruithe. teocht, brú, comhéifeacht athraonta, tiúchan agus timpeallacht sheachtrach eile.
Tá an Braiteoir Taise Hygrometer Grating Fiber pacáistithe le feadán miotail cruach dhosmálta, agus úsáidtear a íogaireacht taise chun monatóireacht a dhéanamh ar thaise. Tá an braiteoir sábháilte go bunúsach, saor ó chur isteach leictreamaighnéadach le haghaidh tástála teochta agus taise.
A Phase Shifted FBG Fiber Bragg Grating introduces phase discontinuities into a fiber grating, creating a narrow transmission window in the FBG's reflection spectrum. The transmission wavelength varies with the amount of phase shift. Phase-shifted FBGs can be used as demultiplexers in dense wavelength division multiplexing (DWDM) systems. The magnitude, location, and point of the phase shift have a significant impact on the performance of the demultiplexer.
The wavelength of a pump laser diode varies at different operating temperatures. The 980nm pump FBG Fiber Bragg grating wavelength lock is used to stabilize the wavelength and intensity of the optically amplified pump laser. By precisely locking the pump laser diode through feedback of a small portion of the laser signal, this type of control significantly improves the power and wavelength output accuracy and reliability of the pump laser. Specifically, it eliminates spectral mode jumps in the pump laser, reduces power intensity fluctuations caused by temperature and pump drive current variations, and greatly improves the performance of the pump laser. It is also commonly used for stabilizing distributed feedback lasers in wavelength division multiplexing systems, the optical path of tunable lasers, and fiber resonators in Raman systems. Depending on the customer's locking requirements for the pump laser, single-grating or dual-grating configurations are available. The dual-grating configuration further improves the output spectral characteristics of uncooled pump lasers.
