The WSF series of wavelength suppression filters are band-stop all-fiber filters that allow to block the transmission of a wavelength or a range of wavelengths over a specified bandwidth.
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 be safely extracted out. WSF band-stop filters are useful in many applications including tandem or in-band pumping, spectroscopy, biomedical imaging, microscopy, or other life sciences or scientific applications.
TeraXion’s proprietary FBG manufacturing process allows for a wide reflection bandwidth and low-loss reflectors, resulting in reduced non-linear effects and highly effective lasers.
