SHG Imaging Technique for Assessing Hybrid EO Polymer/Silicon Photonic Integrated Circuits
Scientists at the University of Arizona have developed a system for assessing the efficiency of the electro-optic (EO) polymer poling process by using multi-photon imaging in the second harmonic generation mode (SHG), permitting imaging and assessment of waveguide devices, including poled polymer devices, prior to, during, and after fabrication. This...
