TLDR
In this article, an electro-optic coefficient r33 value of 10.8 pm/V measured at 1.52 μm was achieved, and the electrooptic activity maintained more than 80% of its initial value after 600 h at 120°C, and more than 60% after 700 h at 150°C.Abstract:
Guest–host poled polymers with large nonresonant electro‐optic activity and high temperature stability were obtained using heteroaromatic chromophores and high temperature optical polyimides. An electro‐optic coefficient r33 value of 10.8 pm/V measured at 1.52 μm was achieved. The electro‐optic activity maintained more than 80% of its initial value after 600 h at 120 °C, and more than 60% after 700 h at 150 °C.read more

Design and synthesis of chromophores and polymers for electro-optic and photorefractive applications
TL;DR: The ability of nonlinear optical materials to transmit, process and store information forms the basis of emerging optoelectronic and photonic technologies as discussed by the authors, where organic chromophore-containing polymers, in which the refractive index can be controlled by light or an electric field, are expected to play an important role.
