Abstract
Diese Aufgabe wird dadurch gelöst, daß in der Koppelblende (KB) Koppelöffnungen (K1, K2) so angeordnet sind, daß darüber für zwei voneinander unabhängige Wellenmoden Kopplungen (TE11n, TM01m) stattfinden und daß über mindestens eine der Koppelöffnungen eine Verkopplung der beiden Wellenmoden und über mindestens eine der anderen Koppelöffnungen ebenfalls eine gleich große, aber entgegengesetzte Verkopplung erfolgt, so daß sich diese beiden entgegengesetzten Verkopplungen gegenseitig aufheben.
