Abstract :
Two-dimensional squint-free radio beam steering by means of single-parameter tuning is proposed, based on a novel optical integrated circuit concept featuring step-wise wavelength-tunable interleaved true-time-delay stages. The tuning functionality of an elementary TTD stage is demonstrated.
