FREE-SPACE OPTICAL INTERCONNECTIONS WITH LIQUID-CRYSTAL MICROPRISM ARRAYS

摘要

Liquid-crystal microprism arrays are shown to be useful for providing electrically controlled alignment of optical beams and fixed various free-space optical interconnections. They can deflect closely spaced micro-optical beams individually to any position with high transmittance (95%), high deflection angle (similar to 10 degrees), and low voltage (<2.8 V-rms). Various fixed optical interconnections can be made simply by changes in the voltages applied to the microprism. [References: 19]
