“…To testify the photonic controllability of the terahertz wave, we made an arrayed photomixer with integrated terahertz antennas. As shown in Figure 3, four UTC-PDs are arranged in a direction parallel to the array with an interval of 0.5 mm, which is a half-wavelength of 300 GHz [12]. Each UTC-PD is connected to four slot antennas aligned in the direction perpendicular to the array so that a total of 16 antennas are arranged in a 4 × 4 two-dimensional configuration.…”

Beam forming and beam steering are inevitable technologies for the practical application of high-frequency electromagnetic waves. Specifically, beam control technology using a phased array for terahertz waves above 100 GHz is necessary to realize the future of high-speed wireless communication. By photomixing, which is a promising method for generating terahertz waves, the phase of the generated waves can be tuned in the optical domain, so that the beam from the phased array can be controlled by photonics technologies. Directing the beam of a terahertz wave enables wireless communication to be improved not only via an increase in power efficiency but also in security in the physical layer of the wireless transmission. By utilizing this advantage and using coherent detection at the receiver, a secured wireless communication system is proposed, and the fundamental mechanism is demonstrated in a feasibility experiment.

“…In contrast, the PIN photodiode (PIN-PD) structure, which is simpler than its UTC counterpart [2], was thought to have lower bandwidth and output power [3]. For packaging of PDs into the mm-Wave/THz RF front-end modules, three main approaches are used; rectangular waveguide [4], [5], dielectric lens [3], [6] and planar antennas [7], [8]. While each offers its own advantage and application, the former technique allows using standard components such as amplifiers and horn antennas.…”

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 WR-12. We demonstrate achieving an output RF power of more than -0.985 dBm (797 μW) at 70 GH frequency.

“…The reason why we chose photomixing is the advantageous features that the phase of terahertz wave depends on the lightwaves' path length and can be tuned easily. Using this feature, we aligned the phases of the terahertz waves from arrayed photomixers so as to be constructively interfered with each other and realized terahertz power combining and focusing at 300 24,25) and 600 GHz. 26) For future higher-rate wireless transmission, it is necessary to confirm the feasibility of this technology at higher frequencies.…”

We investigated the feasibility of terahertz wave beam combination with optical phase control using arrayed photomixers at 700 GHz which is the upper region at the 600-700 GHz atmospheric window. Experimental results showed that combined power superlinearly increases with the number of photomixers/antennas, which follows the array antenna theory, and becomes ten times at four arrayed configuration. This confirms that the wave combination with a directional gain is enabled at 600-700 GHz band by the photonics technology.
