A polarization encoded all-optical scheme for a binary-(radix = 2)-to-quaternary (radx = 4) encoder and a quaternary-to-binary decoder is proposed and described, which is simple, practical and useful for future all- optical information processing.Abstract:
A polarization encoded all-optical scheme for a binary-(radix = 2)-to-quaternary (radix = 4) encoder and a quaternary-to-binary decoder is proposed and described. The performance of the proposed circuit is verified through numerical calculation. In this all-optical scheme, the numbers are represented by different discrete polarized states of light. The model is simple, practical and useful for future all-optical information processing.read more
