An all-optical frequency encoded BCD data addition

  • Sisir Kumar Garai


Addition of binary coded decimal (BCD) data is very important in optical computing and optical signal processing. In this article the author proposes a method of developing all-optical frequency encoded BCD adder exploiting frequency conversion and polarization switching action of semiconductor optical amplifier (SOA). Frequency encoded BCD data offer more advantages over conventionally encoded data in terms of less probability of bit errors and greater reliability. Again efficient frequency conversion and faster switching action of SOA with good on-off contrast ratio makes the scheme attractive.
