✦ Synopsis

Metal-film fiber attenuators have been designed, fabricated, and tested. The devices feature a constant attenuation in the wavelength range 1.2᎐1.6 Ž . Ž . m, short overall length f 20 mm , high return loss ) 50 dB , and low cost. After reviewing the manufacturing procedure, we show that an accurate finishing of the fiber end before metal deposition is a key point in increasing repeatability and reducing dispersion of the absolute attenuation value.
