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.
