Millimetre-wave Photonic Emitter Featuring a PIN-PD with WR-12 Output

We present a photonics based compact broadband emitter module for millimetre-wave signal generation, operating in the E-Band (60 – 90 GHz). A low-loss RF hybrid integration technique is developed to assemble a high-speed and high-power InGaAs/InGaAsP PIN photodiode (PIN-PD) chip into a rectangular waveguide package with WR12. We demonstrate achieving an output RF power of more than -0.985 dBm (797 $\mu$W) at 70 GH frequency.
