Crystal growth, measurement and modeling of the optical activity of $\alpha$-GeO${}_2$. Comparison with $\alpha$-SiO${}_2$

Alexandra Pena, Corinne Felix, Bertrand Menaert +1

This work aimed first at growing high quality bulk $\alpha$-GeO${}_2$ crystals in their Quartz iso-structural form ($\alpha$-SiO${}_2$), using a high temperature flux method. By optimizing the f…
