WAVELENGTH-SELECTIVE SWITCHING DEVICE

摘要

The invention relates to a wavelength-selective switching device. The inventive device comprises: a first waveguide (10) having one input and one output; a second waveguide (12) which has a first output and which intersects with the first waveguide; a first resonant cavity (20) which, for a first wavelength ( lambda 1), connects the input part of the first waveguide to the first output part of the second waveguide, in order to send the signals with the first wavelength ( lambda 1) towards the first output of the second waveguide; and a second resonant cavity (22) which, for a second wavelength ( lambda 2), connects the output part of the first waveguide and the part of the second waveguide opposite the first output thereof, in order to send the signals with the second wavelength ( lambda 2) towards the first output of the second waveguide.
