Ultralow voltage imprinting in GeS2–Ga2S3–AgI glasses for visible to middle-infrared diffraction gratings

Microstructured SHG patterns on Sm2O3-doped borophosphate niobium glasses by laser-induced thermal poling

“…However, some important optical properties, such as microstructured SHG patterns, are seldom reported. Our recent works showed that periodic microstructured SHG or gradient refractive index could be imprinted on BPN glass or other glasses with patterned Si and microstructured ITO as anode electrodes [3,[15], [16], [17], [18]].…”
