“…Array-factor modulation has been demonstrated in a planar multilayer stack [6] in which each layer contains a planar electro-optical waveguide and control electrodes; tuneable stripe channel diode lasers [7,8]; and surface gratings with wavelength tuneable lasers [9,10]. More recently, electro-optic semiconductor devices using GaAs/AlGaAs have been fabricated, and have also employed either element-factor or array-factor modulation.…”

Device concepts for two-dimensional phased-array optics are formulated.Dielectric waveguide optics and electro-optical organic materials can be used to make multiple layers of electro-optically controlled channel waveguides and artificial prisms. Combining element scanning, array scanning, and nonuniform spacing of elements yield devices with increased resolution and reduced side-lobes. These techniques permit the fabrication of two-dimensional phase spatial-light-modulators which are applicable to two-dimensional beam scanning, wavefront shaping, dynamic lenses, and sensors.The electromagnetic field distribution of the light, in amplitude and phase, is specified by the function P.

“…Because of high electro-optical coefficient, low optical loss and high resistance, the intrinsic semiconductor layers constitute optical channels. Because of fine electrical conductivity and high optical loss, the doped semiconductor layers constitute electric poles [2]. When each unit is applied a proper electric field, the wave-guide array is equivalent to electrically controlled optical grating and the small angle adjusting and big angle scanning can be achieved.…”

Based on the programmable phase modulation technique with a multi-channel optical wave-guide array, a novel method used for collimated laser precision scanning was presented. Optical system and control circuit have been designed for the multi-channel optical wave-guide array. Theoretical analysis and experimental result shows that the method can be used for small angle adjusting and big angle scanning of collimated laser in free space light communication.
