Photorefractive effect in undoped aluminum nitride

T Nagai, R Fujimura, T Shimura, K Kuroda - Optics letters, 2010 - opg.optica.org
We report our observation of the photorefractive effect in undoped aluminum nitride. We
measured the coupling constant and the formation rate as a function of pump intensity at a …

Photorefractive effect in Fe-doped GaN

H Kiyama, R Fujimura, T Shimura, K Kuroda - Optics communications, 2009 - Elsevier
The photorefractive effect was observed in Fe-doped semi-insulating GaN. We measured
the two-beam coupling constant and the grating formation time as a function of pump …
