Abstract

LA RADIACION ELECTROMAGNETICA SE MODULA EN RESPUESTA A UNA SEÑAL ELECTRICA QUE PRODUCE UN CAMPO ELECTRICO VARIABLE EN UN SEMICONDUCTOR IMPURIFICADO. EL DISPOSITIVO RESULTANTE TIENE UN AMPLIO CAMPO DE LONGITUDES DE ONDA EN EL QUE PUEDE MODULARSE LA INTENSIDAD DE LA LUZ, ALTO COEFICIENTE DE CONTRASTE ENTRE LOS ESTADOS TRANSPARENTE Y OPACO, BAJO VOLTAJE DE FUNCIONAMIENTO Y ALTA VELOCIDAD, COMO ES DESEABLE EN LAS APLICACIONES DE COMUNICACIONES OPTICAS.
