- We developed a polyimide side-chain polymer under the key guidelines of low losses at interacting wavelengths and high nonlinearity as well as thermal stability and fabricated quasi-phase-matched waveguide devices for second harmonic generation (SHG) and difference frequency generation (DFG). In addition, waveguide structures and periodic poling electrode widths were optimized for large mode overlap and efficient phase matching between the interacting optical fields (0.775 and 1.55 μm), respectively. The polymeric waveguide (1 cm length) records a normalized SHG efficiency of 5.4% W-1 cm-2 and demonstrates DFG with -50 dB conversion efficiency for an input pump power of 10 mW (cw) at room temperature. © 2006 American Institute of Physics.
