摘要：

Terahertz (THz) beam steering is demonstrated based on the phased-array antenna principle without using actual phase shifters. A periodically-poled lithium niobate crystal is pumped with infrared radiation generated from a dual-wavelength optical parametric oscillator. The THz radiation is generated from the crystal via difference-frequency mixing and the emission angle could be varied by tilting one of the incident pump beams. This effect is equivalent to using a phase-shifter array for tilting the phase front of the THz radiation. This technique has the advantage of high speed, wide angular range, and compactness compared to conventional beam steering methods. (C) 2009 The Japan Society of Applied Physics
