Optical scheme of conversion of a positionally encoded decimal digit to frequency encoded Boolean form using Mach–Zehnder interferometer-based semiconductor optical amplifier

The conversion of decimal number to its equivalent binary one and vice-versa is very important in the field of electronic/optical computing and data processing system. There are so many well established methods for this conversion. In this study, the authors propose a new scheme for optical conversion of a decimal number to its frequency encoded binary equivalent using tree architecture-based system and frequency-encoding principle. To implement the above conversion, some optical non-linear switches, such as Mach–Zehnder interferometer-based semiconductor optical amplifier (SOA), reflecting SOA based on SOA, have been used to get frequency encoded response.
