Abstract

We have analyzed and designed an organic high speed digital optical switch (DOS) based on transverse electro-optic effect. In analysis section, we proposed a quantum photonic model (QPM) to explain linear electro-optic (EO) effect. This model interpret this effect by photon-electron interaction in attosecond regime. We simulate applied electric field on molecule and crystal by Monte-Carlo method in time domain. We show how a waveguide response to an optical signal with different wavelengths when a transverse electric field applied to the waveguide. In design section, we configure conceptually a 2 * 2 EO switch with full adiabatic coupler. In this DOS, we use a rib waveguides that its core has been constructed from NPP crystal. This switch is smaller at least to one-half of similar DOS in dimensions.
