Abstract
An optical coupling arrangement consist of a pair of strip-type optical waveguide end segments extending alongside one another and having ends arranged at a small distance from each other so that crosstalk can occur. In order to suppress the crosstalk at a point spaced from the ends of each of the end segments, the segments are arranged so that the distance from one another increases from the distance at the end as the distance from the end along said segments increases.
