Opto-logic Gate Implementation via Liquid Crystal Molecules: An Understanding Toward Optical Information Processing

Liquid crystals (LCs) are used to fabricate advanced electronic/optical devices for information processing by implementing logic gates. LCs, known for their unique light modulation with an electric field, are utilized to build logic/opto-logic gates. The study involves the formulation and comprehension of logic gates via LC characterization. It assesses their feasibility in digital systems, highlighting advantages like low power use and compatibility with existing techniques. The work discusses several experimental results, demonstrating the performance and reliability of LC logic gates compared with traditional semiconductor-based ones. The study looks into new ways to use LC technology beyond just screening, exploring different uses in computing, leading to creative and energy-efficient solutions.
