SIOM Proposes 3D-Printed Active Glass Approach
Start here
A team at the Shanghai Institute of Optics and Fine Mechanics proposed a new 3D-printed active glass approach for integrated photonic devices. Combining molecularly designed sol-gel chemistry with DLP 3D printing, the approach enables low-temperature fabrication of rare-earth-doped active glass and formation of complex three-dimensional structures. The study produced transparent amorphous glass at a sintering temperature of 900 degrees C and extended the process to neodymium-, erbium-, and ytterbium-doped systems. The results were published in Additive Manufacturing. An erbium/ytterbium co-doped glass waveguide achieved a maximum on-off gain of 2.57 dB/mm at 1551 nm under 976 nm pumping.
