摘要：

We demonstrate single-lobe beam-steering at lambda= 460-478 nm using an end-fire optical phased array coupled to a free-propagation region slab and convex grating for out-of-plane emission. Our design achieves sidelobe-free steering over 57% of the total maximum steering range 100 mu m away from the OPA. The devices were implemented in silicon nitride waveguides and integrated on implantable silicon neural probes for targeted optogenetics.
