Abstract

In a phased-array filter, mutually spatially separated planar waveguides arranged on the surface of a substrate between two substrate edges are optically connected to one another by an optical phase shift in the form of a plurality of strip-type optical waveguides which extend in a bent fashion and are of different optical length. In order to be able to continuously adjust the central wavelength of the filter by varying the location of launching within certain limits, a planar waveguide is arranged directly at the other substrate edge so as to permit direct launching into this planar waveguide.
