We present a two-dimensional (2D) optical phased array (OPA) with 8× 8 elements in which
light is electro-optically controlled by silicon phase modulators. The randomly distributed …

The general formula for the probability of radiation of a twisted photon by a classical current
is derived. The general theory of generation of twisted photons by undulators is developed. It …

Radio-over-Free-Space-Optics (Ro-FSO) is a promising technology for future wireless
