Photonic, Plasmonic, Fluidic, and Luminescent Devices Based on New Polyfunctional Photo-Thermo-Refractive Glass

Micro-integrated high-power narrow-linewidth external-cavity tapered diode laser at 808 nm

“…For a DBR grating based on AlGaAs, the influence of the thermal expansion is negligible compared with that of the thermo-optic effect [28]. For a VBG based on photosensitive glass, in contrast, the influence of the thermo-optic effect is negligible compared with that of the thermal expansion [29]. The influence of the thermo-optic effect on a DBR grating is around one order of magnitude higher than the effect of the thermal expansion on a VBG [28,29].…”

The influence of the thermo-optic effect on a DBR grating is around one order of magnitude higher than the effect of the thermal expansion on a VBG [28,29]. This is the reason that the wavelength of the ECDL based on a VBG is much more stable when the operating temperature is increased.…”

A comparative study of photocatalytic activity of Na+–Ag+ ion-exchanged glass-ceramics with metallic Ag, semiconductor AgBr, and hybrid Ag–AgBr nanoparticles

“…Photo-thermo-refractive glass is an excellent example of such materials, where the subsequent growth of Ag-AgBr-NaF phases allows the volume of Bragg gratings to be recorded with a diffraction efficiency of above 99% and facilitates the use of this glass-ceramic in industry. 36 It is worth noting that such hybrid metal-semiconductor photocatalysts, particularly Ag-AgCl, Ag-AgBr, and Ag-AgI, synthesized by chemical methods are characterized by excellent photocatalytic performance according to the published works. [37][38][39][40] As only surface crystallization is important for photocatalytic applications of glass-ceramics, ion exchange technique is a promising tool.…”
