Upgraded beamforming architectures based on the optical butler matrix

A novel optical beamforming architecture based in optical Butler Matrices has been proposed. This architecture has straightforward multi-beam applications, reducing the number of optical components required. Besides the benefits derived from its photonic nature (low loss/size, huge bandwidth, etc), this architecture allows simultaneous and independent control of all beams, increasing significantly the flexibility of the beamforming network.

This novel optical beamforming network offers several advantages with respect to other approaches, such as flexibility or reduced number of required components, besides the known advantages of using a photonic beamformer with regard of traditional ones based either in DSPs or RF/IF beamforming. In particular, this architecture is useful to implement SDMA networks, due to its capability to generate and steer N-beams independently. The ability to shape and steer a beam, may be of interest to manufacturers and service providers as allows improving the performance of wireless networks and the implementation of advanced features such as user location and tracking or overcoming service drops.
