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 …

Evaluation of InP: Fe parameters by measurement of two wave mixing photorefractive and absorptive gain
In this paper, we present two-wave mixing absorption gain measurements in InP: Fe in the
960–1035 nm wavelength range. The measured absorption gain is shown to be positive for …
