novel ring resonator based integrated photonic beamformer for broadband phased array receive antennas part i design and performance analysis
Journal of Lightwave Technology, 2010Co-Authors: Arjan Meijerink, Leimeng Zhuang, C.g.h. Roeloffzen, David Marpaung, R Meijerink, M J Bentum, Maurizio Burla, J Verpoorte, P Jorna, A HulzingaAbstract:A novel Optical beamformer concept is introduced that can be used for seamless control of the reception angle in broadband wireless receivers employing a large phased array antenna (PAA). The core of this beamformer is an Optical beamforming network (OBFN), using ring resonator-based broadband delays, and coherent Optical Combining. The electro-Optical conversion is performed by means of single-sideband suppressed carrier modulation, employing a common laser, Mach-Zehnder modulators, and a common Optical sideband filter after the OBFN. The unmodulated laser signal is then re-injected in order to perform balanced coherent Optical detection, for the opto-electrical conversion. This scheme minimizes the requirements on the complexity of the OBFN, and has potential for compact realization by means of full integration on chip. The impact of the Optical beamformer concept on the performance of the full receiver system is analyzed, by modeling the combination of the PAA and the beamformer as an equivalent two-port RF system. The results are illustrated by a numerical example of a PAA receiver for satellite TV reception, showing that - when properly designed - the beamformer hardly affects the sensitivity of the receiver.

Broadband phased array antenna steering by means of coherent signal Combining in an integrated ring resonator-based Optical beamformer
2008Co-Authors: Leimeng Zhuang, Arjan Meijerink, C.g.h. Roeloffzen, David Marpaung, Rene Heideman, M. Hoekman, Arne Leinse, Wim Van EttenAbstract:A squint-free, continuously tunable Optical beamformer for broadband phased array receive antennas is proposed. The complete system is demonstrated, including E/O and O/E conversions, and Optical signal processing. The latter involves delay synchronization and coherent Optical Combining, which is performed in an integrated ring resonator-based Optical beam forming network, realized in low-loss, CMOScompatible TriPleX technology. Successful combination of four beamformer input channels has been demonstrated by means of RF-to-RF measurements.
