Photonic integration is very promising to bring down volume and weight of phased-array beamforming networks. In addition, photonics allows for increased functionality for widebandwidth systems. In this paper we demonstrate the feasibility of phase and amplitude control of a 16-element phased-array antenna with a single InP integrated circuit. The concept and design of an optical phase locked lo...

With the advance of mature fabrication technologies, photonic integrated circuits (PICs) reach ever-higher levels of complexity. Integration of thousands of components has been shown [1], with each main technology showing an exponential growth in complexity [2]. This increase in complexity requires a convergence in technologies, and the roadmaps are currently being pushed by silicon nitride, (h...
