The glass core is doped with an Erbium in periodic segments of the fiber.
Layers of high index ?and low index ?material are deposited on a glass substrate.
Thin layers of silica glass are placed onto wafers to produce a prism-like effect.
Fiber is etched with an ultraviolet laser that is precisely spaced for specific wavelength filtering.
