Full-Optical Logical Gates for Optical Signal Processing

This paper is dedicated to full-optical logical NOT, AND and NAND gates. In the first section are described logical functions based on Mach-Zehnder interferometric structure. The second part deals with full-optical logical gate AND, that utilizes TOAD structure. The last one is focused on the exploitation of logical gate AND for optical head separation from payload data. Simulations and final design were realized in simulation environment Virtual Photonic close up to 150 Gb.s-1 bit rate.
