1270nm nganti 1610nm utawa 1550nm Fiber Bragg Grating FBGs minangka jinis kisi difraksi sing dibentuk kanthi modulasi indeks bias inti serat kanthi cara tartamtu. Iku piranti Filter pasif. Serat grating digunakake akeh ing bidang komunikasi serat optik, sensing serat optik lan pangolahan sinyal serat optik amarga ukurane cilik, mundhut fusi sing kurang, kompatibilitas lengkap karo serat optik lan bahan cerdas sing dipasang, lan dawa gelombang resonansi sensitif marang owah-owahan. suhu, galur, indeks bias, konsentrasi lan lingkungan njaba liyane.
Sensor Kelembapan Higrometer Fiber Grating dikemas karo tabung logam stainless steel, lan sensitivitas kelembapan digunakake kanggo ngawasi kelembapan. Sensor intrinsik aman, bebas saka gangguan elektromagnetik kanggo tes suhu lan kelembapan.
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.
