WaveCapture FBG Analyzer Series
Precise , reliable , and compact spectral analyzer for Fiber Bragg Grating ( FBG ) sensing
Advanced Energy ’ s WaveCapture Fiber Bragg Grating Analyzer ( FBGA ) is an integrated spectral engine that serves as the heart of precise , fast , and reliable FBG interrogator systems . The FBG Analyzer employs a proprietary optical design that features high-efficiency dispersive optics , an ultrasensitive detector array , and innovative numerical algorithms to provide high speed , high-resolution spectral measurements in challenging environments .
A broadband light source illuminates an optical fiber which features an array of “ N ” fiber bragg grating sensors . The FBG array reflects “ N ” spectral bands of light back down the fiber , where an optical circulator directs the light to the FBG Analyzer . Inside the analyzer , the light is dispersed and the diffracted spectrum is measured by a detector array . Numerical algorithms are used to extract each “ Bragg wavelengths ” from the raw data , which are sent to the host and converted to temperature , strain , acceleration , or other measured parameter . Both raw and processed data are available to the host .

CTL Continuously Tunable Laser family : Measurements at the quantum limit
Lasers of TOPTICA ’ s CTL product family are made to be ideal tools for exciting microcavities or quantum dots , for pumping micro combs , as well as for component testing and spectroscopy . Their most important property is providing wide and continuous tunability without any mode-hops . They have high power , a narrow linewidth and low drift . Scans can be performed with highest resolution . This unique combination of features makes them outstanding in their field and enables researchers to perform measurements at the quantum limit .
The latest addition to this family is called CTL 900 . It is tunable between 880nm and 950nm . The long-awaited wavelength range is especially useful for resonantly exciting quantum dots , for spectroscopy or addressing e . g . rare earth ions or the Caesium D1 line .
