Abstract :
Terahertz (THz) beam steering is demonstrated based on the phased-array antenna principle without using actual phase shifters. The THz radiation angle from lithium niobate crystal can be varied by adjusting the incidence angle of the pump beam. This technique has advantage of high speed, wide angular range compared to conventional steering methods.
