This manuscript proposes the combination of several photomixing THz sources for overcoming the power limitations of this technology. Each element is placed in the gap of a balanced antenna. All the elements conform a 2D rectangular array. For avoiding issues related to having out-of-focus sources when using one electrically large silicon lens, two different strategies are considered: increasing the density of elements by using a compact design and using an array of dielectric rod waveguide antennas instead of the lens. Experimental considerations are also provided for two prototypes manufactured in the 1550 nm window. Measured power level will be shown at the conference.
