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: Optically transparent, conductive electrodes (12) are formed on a semi-insulating gallium arsenide substrate (10) by a blanket ion implantation of a suitable dopant followed by an annealing step to provide an electrically conductive crystalline structure. The electrode pattern is masked via a photoresist (14), and the exposed regions (16) are bombarded by boron ions which damage the ordered crystalline structure. The resulting device has improved interelectrode electric isolation.

Abstract: A liquid crystal cell (40) has two infra-red transparent windows (42) and liquid crystal molecules (50) in the space between. At least one of the windows (42) is a sheet of infra-red transparent, semi-insulating crystalline material, such as gallium arsenide, having an ion implanted surface region (44). The sheet (42) is annealed after ion implantation to electrically actuate the implanted ions. The sheet (42) has uniform infra-red transmission characteristics over its surface and is provided with anti-­reflection layers (46 and 47). An electric potential (V) can be applied from a source (56) to the two windows (42) to establish an electric field (E) in the cell and thereby electrically orient the liquid crystal molecules (50).
