Ultra-Low-Loss Silicon Nitride Optical Beamforming Network for Wideband Wireless Applications

Three optical ring resonator (ORR)-based integrated ultra-low-loss silicon nitride 1 × 4 optical beamforming networks (OBFNs) for millimeter-wave (mmW) beamsteering are reported. The group delay ripple of multi-ORR delay line was theoretically optimized and quantitatively studied by applying a genet...
