    OPTICAL MATERIALS: 'On-silicon' engineered substrates speed photonic device development

    David Williams
    April 1, 2013
    Thick (3-10 μm) engineered "on-silicon" substrates—some with rare-earth oxides—are being fabricated to meet high-volume demands for current and next-generation photonic devices...
