All-optical decimal to ternary converter with the proper use of optical non-linear material

摘要

An all-optical system to convert the decimal number to ternary number is proposed here with the proper use of switching mechanism of Kerr-type optical nonlinear material. In this scheme the intensity level I, 2I, 3I, 4I, respectively, represents the decimal number 1, 2, 3, 4 which is used as the input bit. The output of the optical ternary state is represented by the absence of light (0), the presence of light with intensity level I (1) and the light of 2I intensity [1 bar (1)]. Beam splitter and beam combiner are used here to maintain the desire intensity level.
