Abstract: For electrically addressing the extremely large number and high density of phase shifters (30,50,42) needed for operation of an optical phased-array beam steerer (52), the array of phase shifters is divided into identical subarrays (38) which completely fill an optical aperture. All subarrays (38) are connected electrically in parallel by electrically interconnecting corresponding electrodes (32) of each subarray (38). Thus, the number of external electrical leads (36) required for addressing the fully array is reduced to the number of phase shifters in a single subarray (38).

Abstract: An optical beam phase shifter includes a liquid crystal cell (20) having an optically-transparent common electrode (30) on a first window (22) and a multiplicity of parallel stripes electrodes (32) on the second window (26). A multiplicity of control signals are applied between the individual stripe electrodes (32) and the common electrode (30), thereby creating local variations of the refractive index of the liquid crystal molecules (24), which variations cause differential phase shifts across the cross section of a light beam incident thereon. The control signals are applied to contact pads (36) affixed to an external surface of the liquid crystal cell (20), which contact pads (36) underlie a plurality of the stripe electrodes (32). A multiplicity of conductors (34) extend through a transparent insulating layer (40) to couple the control signals to the stripe electrodes (32). The stripe electrodes (32) are optically-transparent, and the incident beam is reflected from the contact pads (36). In another embodiment, the stripe electrodes are reflective, and the incident beam is reflected therefrom.

Abstract: For electrically addressing the extremely large number and high density of phase shifters (30,50,42) needed for operation of an optical phase array beam steerer (52), the array of phase shifters (30,50,42) is subdivided into identical subarrays which completely fill an optical aperture. All subarrays are connected electrically in parallel by electrically interconnecting (32) corresponding electrodes (30(i,j) of each subarray. For providing an enhanced number of beam steering positions for the subaperture-addressed beam steerer, each subarray is functionally divided into a number of periods, and to each period of any subarray, a staircase voltage is applied to provide a phase difference of 2π between the phase shifts introduced by the first and last steps of the staircase voltage, each being applied to a respective phase shifter (30,50,42). The number of phase shifters (30,50,42) in each period need not be the same for all periods.

Abstract: An optical beam phase shifter includes a liquid crystal cell having a common electrode (12) on a first windows and a multiplicity of parallel stripe electrodes (14) on a second window. A multiplicity of control signals are applied between the individual stripe electrodes (14) and the common electrode (12), thereby creating local variations of the refractive index of the liquid crystal molecules (13) therebetween, which variations cause differential phase shifts across the cross section of a light beam (18) incident thereon. An optically-refractive element (11), having an index of refraction greater than the index of refraction of the liquid crystal material (13), is interposed between the beam (18) and the liquid crystal material (13). The refractive element, illustratively a prism (11), increases the angle of incidence of the beam (18) entering the liquid crystal material (13), thereby increasing the beam travel distance through the liquid crystal molecules. This allows the use of a thinner layer of liquid crystal molecules, and hence, improved response time of the optical beam phase shifter to changes in the control signals, and reduced fringing effects between stripe electrodes (14).
