Abstract :
All-optical 5-bit binary coded decimal (BCD) to binary converter has been designed with the help of Semiconductor Optical Amplifier (SOA) - assisted Sagnac switches. Binary is handy because we can easily use something physical to represent numbers. We use laser source for incoming pulse and input data. When it is on, it means 1-state and when it is off, it means 0-state. The paper describes all-optical conversion scheme using a set of all-optical NOT and AND gates. The circuit can perform the conversion at very high speed. The operations of the circuit are studied theoretically. We also make the simulation of this proposed circuit.
