High Efficiency Mono-order Concave Diffraction Grating
Figure 1: Microspectrometer with access waveguides and diffraction grating.PARTNER INSTITUTION: Concordia UniversityBACKGROUNDThe possibility to acquire a spectrum is determinant in sensing for the accurate detection of biological and chemical species, their discrimination, their quantification, and possibly simultaneous identification. In the same...

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...
