Abstract

We consider propagation of surface plasmon polaritons in two-dimensional tapered slot waveguides. We derive an analytical formula for the change of the amplitude of a plasmon mode due to tapering. We show that the taper leads to the field enhancement effectively compensating the mode attenuation due to losses. We obtain numerically the shape of the optimal function of the taper that provides exact loss compensation. (
