Abstract: Electro-optical steering devices based on a single aperture allow an optical beam to be steered in the near field of the device by means of multimode interference mechanisms [1]. We show that a translation of the near field beam steering into far field beam steering can be achieved by applying a curved facet at the output of the steering device. A cylindrical facet of 20 μm radius is etched within an InP electro-optical steering device to enable a far field steering of 5° with a maximum applied voltage of 6 V.
