Abstract

The coupling device comprises a displacement arrangement for displacing the two waveguide end surfaces relative to one another parallel to the end surfaces and the arrangement has an expansion element that moves the end surfaces relative to one another on the basis of a spatial expansion and/or contraction of the element. With this coupling device tunable optical multi-channel filters with temperature compensation, optical attenuators and waveguide switches can advantageously be realized in a simple manner.
