FBG (Fiber Bragg Grating) Alxenses’s offers a series of fiber-optics products based on Fiber Bragg Grating (FBG) technology. FBG is produced in optical silica fibers by creating periodic refractive index variations in the fiber core using UV laser light. FBG is an in-line optical filter and its reflection wavelength and spectral shape depends on the periodicity, length as well as depth of the refractive index changes of the grating structure. FBG exhibits very low loss and is low-cost compared to the bulk-optics counter parts. By altering the grating periodicity and refractive index change, FBGs for various fiber-optics communication and sensing applications can be easily produced. Features: •High reliability and stability •High reflectivity •High side-lobe suppression ratio •Low insertion loss •Narrow bandwidth optical filter •Immunity to EMI •Multiplexing capability Applications: •Strain fiber optics sensor •Temperature fiber optics sensor •Displacement fiber optics sensor •Humidity fiber optics sensor Both Acrylate and Polyimide coated FBGs are available. Note: Acrylate and polyimide are the two common coating materials for optical fiber. The polyimide coating withstands higher operating temperature (up to 300°C) than Acrylate material (up to 85°C). Features: •High reliability and stability •High reflectivity •High side-lobe suppression ratio •Low insertion loss •Narrow bandwidth optical filter •Immunity to EMI •Multiplexing capability Applications: •Strain fiber optics sensor •Temperature fiber optics sensor •Displacement fiber optics sensor •Humidity fiber optics sensor
Short-Length FBG Alxenses’s short-length FBG is fabricated based on advanced FBG fabrication technique and production facilities. The Bragg wavelength and length of the FBG can be controlled precisely while maintaining high reflectivity and side-lobe suppression ratio. The standard length of short-length FBG is 3mm and can be customized to various lengths upon request. The short-length FBG allows smaller form-factor housing to be used for FBG packaging that is necessary when sensor size is a concern. Short-length FBG is suitable for building small sensors for temperature and strain measurements and compact sensor arrays for distributed monitoring applications. Features: •Short length •Low insertion loss •Multiplexing of FBG sensors in single fiber Applications: •Small form-factor sensor packaging Note: In general, the bandwidth becomes wider when the length of FBG gets shorter.
