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 is simulated and characterized. The probes are used for optogenetic stimulation and calcium imaging.
具有集成纳米光子波导的植入式硅神经探针可以在深度向脑组织提供图案化的动态照明。在这里，我们介绍了具有集成光相控阵的神经探针，并在体外演示了光的转向。模拟和表征了脑组织中的光束形成。这些探针用于光遗传学刺激和钙成像。
