Abstract
An optical device integrated on a planar substrate is disclosed, comprising a Y-branch attenuator optically coupled to a Mach-Zehnder modulator. The device also comprises means for reducing a crosstalk caused by unguided radiation between the Y-branch attenuator and the Mach-Zehnder modulator. In one embodiment, the reduction of the crosstalk is obtained by connecting the Mach-Zehnder modulator to one arm of the Y-branch attenuator. The invention also comprises a transmitting module including the integrated device.
