CA 2397049
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.
L'invention concerne un dispositif optique intégré à un substrat plat, qui comporte un atténuateur à branche en Y optiquement couplé à un modulateur Mach-Zehnder. Le dispositif comporte également des moyens de réduction d'une intermodulation causée par un rayonnement non guidé entre l'atténuateur à branche en Y et le modulateur Mach-Zehnder. Dans un mode de réalisation, la réduction de l'intermodulation s'obtient en reliant le modulateur Mach-Zehnder à un bras de l'atténuateur à branche en Y. L'invention concerne également un module d'émission comprenant le dispositif intégré.
