5 Theoretical Predictions of Electro-Optic (EO) Effects in Polymer Wires

One of the important applications of molecular layer deposition (MLD) is nonlinear optical polymers that are the key materials for photonic devices such as light modulators, optical switches, tunable filters, wavelength converters, and so on.

In the present chapter, nonlinear optical effects, especially EO effects in polymer wires with designated molecular sequences, are predicted theoretically [1, 2 and 3].

5.1 Molecular Orbital Method

In order to design EO polymer wires, the molecular orbital (MO) method is used. In the present section, the MO method is briefly reviewed.

Figure 5.1 shows models for Hamiltonian in the MO calculations. In this example, the system consists ...
