Abstract
We propose a new procedure for evaluating the complex refractive index of a metal film, based on transmission measurements at different inci dence angles. The method is simpler and faster than standard ellipsome try and performs the accuracy required for the design of fiber-optic a ttenuators for telecommunications. As an example, we report on a devic e showing a constant attenuation on the 1200-1600-nm wavelength range. (C) 1998 Optical Society of America.
