摘要：The invention relates to a method and to an apparatus for compensating thepolarization-dependent shift of the centre frequency in an optical filter containing aninterferometer by way of compensating for the birefringency in at least one waveguide ofthe interferometer, wherein at least one λ2-plate is inserted into the beam path of theinterferometer and the at least one waveguide (16, 17) is brought to a specifiabletemperature at least in sections on the right and left of the λ2-plate (11) and at least onesection on the right of the λ2-plate (11) is brought to a first temperature T1 and at leastone section on the left of the λ2-plate (11) is brought to a second temperature T2.
