Zusammenfassung:High power W-band integrated photonic emitters were successfully demonstrated by the integration of modified unitraveling-carrier photodiodes (PDs) with high directional gain Vivaldi antennas. An impedance matching network was designed to achieve conjugate matching between the PD and the antenna for better power delivery. An effective isotropic radiation power as high as 5 dBm at 110 GHz was measured for the emitter with a 5- \mu \text{m} -diameter PD. The impedance matching was shown to significantly affect the effective isotropic radiation power.
