TeraXion Launches New Range of High-Power, All-Fiber Bragg Grating Notch Filters

Quebec City, December 6, 2023 –

TeraXion, photonic leader, is pleased to launch a new range of high-power, all-fiber Bragg grating notch filters. 

The WSF series are all-fiber band-stop (notch) filters that are used to selectively attenuate or block a wavelength or a range of wavelengths while allowing other wavelengths to pass through. Using TeraXion’s exclusive tilted FBG filter technology, the WSF cleverly guides unwanted signals through the cladding of the fiber where it can finally be safely extracted out.

Pascal Deladurantaye, Laser Systems Director, comments: "The WSF series stands out for its ease of integration into fiber laser systems, eliminating the need for any other component. This filter has also proven its excellence in 1018 nm applications by blocking the back-propagating signal from the power amplifier, thereby helping to increase the power and efficiency of tandem-pumped fiber lasers."

WSF notch filters are useful in many applications, including tandem or intra-band pumping, spectroscopy, biomedical imaging, microscopy or other scientific or life science applications.
