ABSTRACT:
An integrated optical device for tapping signal power provides a tap which is substantially independent of wavelength and polarization. The optical device includes a first tap consisting of a first optical waveguide carrying an input signal S disposed in coupling relation with a second optical waveguide for providing an output cross-state transmission T.sub.1. The cross-state transmission T.sub.1 is polarization and wavelength dependent. The optical device further includes a second tap consisting of a third optical waveguide disposed in coupling relation with and in series with the second optical waveguide carrying the output cross-state transmission T.sub.1 for providing an output bar-state transmission T.sub.2. The bar-state transmission T.sub.2 has an opposite dependency on waveguide coupling than that of the cross-state transmission T.sub.1 and, thus, compensates for wavelength and polarization dependencies of the cross-state transmission signal T.sub.1, thereby providing an overall tap transmission T which is equal to T.sub.1 T.sub.2 and is substantially independent of polarization and wavelength.
