| Summary:
Implantable silicon neural probes with integrated nanophotonic waveguides can
deliver patterned dynamic illumination into brain tissue at depth. Here, we
introduce neural probes with integrated optical phased arrays and demonstrate
optical beam steering in vitro. Beam formation in brain tissue was simulated
and characterized. The probes were used for optogenetic stimulation and calcium
imaging.
