Phase-encoded binary number systems

Definition

Phase-encoded binary number systems are methods of representing binary information using the phase of a light wave to denote bits. By shifting the phase of light signals, data can be encoded in a way that is highly efficient for optical computing applications, allowing for parallel processing and increased data transmission rates. This encoding technique plays a crucial role in enhancing the performance of optical arithmetic logic units by enabling faster and more reliable data manipulation.
