StockerYale Inc. offers cladding mode suppression fiber for use in gain-flattening filters, for the manufacture of fiber Bragg gratings and for broad-spectrum-bandwidth DWDM applications. The company says the grating is written into the core and cladding, eliminating loss peaks in the transmission spectrum at wavelengths below the main reflection peak. The fiber's photosensitivity increases the grating diameter, suppressing the coupling between core and cladding modes. The fiber is optimized for hydrogen loading, and the numerical aperture and mode-field diameter enable low splice loss to standard single-mode fiber.
