Pagination or Media Count:
We present results on the design and simulation of optical phased arrays made with Si waveguides and Ta scattering elements. We show that multi-element apertures offer advantages in varying the output power level and beam shape, and then demonstrate narrow beams that can be steered by tilde20 degree with thermo-optic tuning.
