Abstract
An optical fiber filter is produced which has a sinusoidal response or a modulated sinusoidal response with any desired amplitude and wavelength period. This is achieved by first producing an elongated adiabatic taper in a single-mode fiber which has been stripped of its protective jacket. Then, on the slope of this adiabatic taper, at each end of the central zone, there is formed a non-adiabatic taper such as to obtain a predetermined sinusoidal or modulated sinusoidal response in the filter.
