array
The present numerical work combines gain switching and external optical feedback to generate pulses with a high level of coherence across a large array of semiconductor lasers. The influence of several parameters such as modulation frequency, feedback strength and frequency detuning is analyzed and this dataset gathers the temporal traces generated with our code, that is adapted from the Lang-Kobayashi model to take into account decayed coupling in an array of lasers.

This work introduces an E-plane hollow waveguide antenna array feeding network to feed 4 units of 2x2 sub-arrays as aperture elements. The feeding network and the sub-arrays are built as one object and fabricated using 3D-printing technology. The material used in 3D-printing is polymer and the cavity of the antenna array with the feeding network were metalized using sufficient layer of conductive silver epoxy. The introduced design exhibits an 18% bandwidth at center frequency of 14 GHz with a gain of 16 dBi.
