Paper Abstract

The linear optical and electro-optical properties of new guest-host poled polymeric thin films are reported based on combined ellipsometric and modulated reflection measurements. Wavelength dispersion of the electro-optic coefficient and comparison between second harmonic generation and electro-optic coefficients are in keeping with a two-level model of the quadratic nonlinearities. The large extension of the conjugated systems may account for the remarkable quasi-absence of relaxation of the electro-optic coefficient over a period of months, when incorporated in PMMA. Operation of a waveguide phase modulator has been demonstrated at 1064 nm in a multilayer strip waveguide architecture over a GaAs substrate, and shown to correspond to r33 equals 1.76 pm/V. Further optimization is underway.
