Abstract
Wavelength division multiplexing (WDM) systems can offer large capacity of the optical fiber communication. However it requires the wavelength selective add-drop filters. A novel tunable wavelength filter, consisting of fiber grating and movable diaphragm, is proposed and fabricated by using a surface micro-machining technology. By moving the diaphragm at near the side polished fiber, the effective refractive index of the fiber core is controlled. This modulation of effective refractive index of the fiber core enables to control the wavelength of the fiber Bragg grating.
