High-Power W-band to G-band Photonically-Driven Electromagnetic Emitter with 8.8 dBm EIRP

In this paper, a wideband high-power photonicallydriven integrated electromagnetic emitter is proposed with operation from W-band through G-band (75 GHz to 220 GHz). The wideband and high-power behaviors are achieved by integrating a high-power charge-compensated modified unitravelling carrier (CC-MUTC) photodiode (PD) with a high-directivity two-arm sinuous antenna. The PD with a diameter of 5 μm achieves a responsivity of 0.2 A/W and a 3-dB bandwidth of 120 GHz. The measurement results indicate that the emitter provides a high effective isotropic radiated power (EIRP) between 75 GHz to 210 GHz, achieving a maximum EIRP of 8.8 dBm at 130 GHz.
