EN EL PRESENTE ARTÍCULO SE DISCUTEN LOS PRINCIPIOS FÍSICOS DE LA DIFRACCIÓN DE LA LUZ POR DOS FOTONES EN CRISTALES Y SE PRESENTA LA POSIBILIDAD DE EXPLOTAR TAL FENÓMENO PARA LA CREACIÓN DE LÓGICA TODO-ÓPTICA. SE PRESENTA TANTO UN CONJUNTO COMPLETO DE OPERACIONES LÓGICAS COMO LA REALIZACIÓN DE UNA MEMORIA DE UN SOLO BIT, QUE HAN SIDO ESTIMADAS Y ANALIZADAS ALGORÍTMICAMENTE.AbstractWE DESCRIBE PHYSICAL PRINCIPLES OF A TWO-PHONON LIGHT SCATTERING IN CRYSTALS AND PRESENT THE FEASIBILITY OF EXPLOITING SUCH A PHENOMENON FOR THE CREATION OF AN ALL-OPTICAL LOGIC. BOTH PERFORMING THE FUNCTIONALLY COMPLETE SET OF LOGIC OPERATIONS AND FULFILLING ONE BIT MEMORY HAVE BEEN ALGORITHMICALLY ANALYZED AND ESTIMATED.WE DESCRIBE PHYSICAL PRINCIPLES OF A TWO-PHONON LIGHT SCATTERING IN CRYSTALS AND PRESENT THE FEASIBILITY OF EXPLOITING SUCH A PHENOMENON FOR THE CREATION OF AN ALL-OPTICAL LOGIC.
