Abstract:The use of photonics for phased array antenna (PAA) control is a vital area of applied research. In particular, the potential impact of compact, low cost, photonically controlled PAAs for large scale global applications, such as wireless communications, is a major business growth area. This paper presents an overview of technology approaches for photonic delay lines (PDLs) as well as the challenges. Polarization based switched PDLs using two-dimensional (2D) liquid-crystal devices are discussed. In particular,… Show more
