An Alternative Approach of Implementation of All Optical Frequency Encoded Logic Gates Using Semiconductor Optical Amplifier Based Ring Lasers

All optical frequency encoded logic gates NOT, OR, AND, NOR and NAND are proposed using semiconductor optical amplifier based ring lasers with frequency filtering by fiber Bragg grating. The output states are controlled by the injection of proper input signals into the ring laser via fiber Bragg grating. The three gates NOT, OR, AND are fundamental and the other two NOR and NAND are universal gates. So any logic processors can be possible to design and integrate.
