Abstract

Progress on mainchain syndioregic polymers for χ⁽²⁾ applications is reported, An electro-optic coefficient, r33, of 8.5 pm/V @ 1.3 microns and loss of < 1 dB/cm was measured in a Mach-Zehnder interferometer waveguide fabricated by parallel plate electrode poling and photobleaching. This EO film has been stable at ambient room temperature for many months, and the long term thermal stablility is estimated to be ≥125°C if protected from UV radiation and air. Preliminary results on the preparation of a series of related polymers designed for low temperature fabrication of χ⁽²⁾ thin films will be reported.
