    We present a phase-shifter and a Mach-Zehnder type modulator that we have realized on n-/n+ GaAs homojonction using classical photolithography techniques. The characterization of the optical components has been performed and shows a 50 V Vπ voltage, a 10 dB extinction ratio and 5 dB insertion loss for the modulator.Nous présentons un déphaseur ainsi qu'un modulateur de type interféromètre de Mach-Zehnder que nous avons réalisés sur homojonction n- /n + GaAs en utilisant des techniques classiques de photolithographie. La caractérisation de ces composants a montré, pour le modulateur, une tension d'extinction de 50 V, un taux d'extinction de 10 dB et des pertes d'insertion de 5 dB

    This work introduces a subsystem level cosimulation for generation, boosting and transmission of millimeter wave signals for 5G applications. The simulation processes to model the full equivalent circuit of uni-Traveling carrier photodiodes based on reflection coefficient measurements are analyzed. The optoelectronic lumped equivalent is co-integrated with a transimpedance amplifier design synthesized by high speed transistors. The proposed broadband component achieves competitive performance characteristics exhibiting high gain
