"ceramics are very powerful in micro-optics due to their light-matter interaction properties... speed of light in vacuum unbeatably fast, but glass and ceramics have higher refractive index, light propagating through suitable material slowing down... 3D-architected ceramics can contribute to optical communication and light circuits with the right material combination and composition... future: developing various resins that change their properties when exposed to light, permitting them to print simultaneously"
