ABSTRACT:
A device for deflecting an incident radiation beam through a steering angle to produce a deflected radiation beam is described. The device comprises a photonic crystal receiving the incident radiation beam at a dynamically controlled incidence angle. The photonic crystal is configured to negatively refract the incident radiation beam such that relatively large controlled variations of the steering angle are provided by relatively small controlled variations of the incidence angle.
