Abstract
In order to overcome the bit-rate limitations caused by Electronic Signal Processing, All-Optical Signal Processing is required. All-Optical Half-Adder and Half-Subtracter can serve as building blocks for All-Optical Arithmetic Logic Unit (ALU). In this paper, a demonstration of All-Optical Half-Adder and Half-Subtracter is done operating at 1 Gbps bit rate using Continuous Wave (CW) Lasers as carrier sources and two Semiconductor Optical Amplifiers (SOA) as basic active elements. One of the arithmetic functions realized by this scheme i.e. Borrow Signal (A ¯ B) exhibited Max Q-factor of 21.2046 to achieve error free operation at bit rate of 1Gbps.
