… The moving grating technique also allows for the determination of the sign of the charge
carriers [12]. In our case, the resonance in the energy transfer occurs when the interference …

We present a new model (including both temperature and electron‐hole effects) of two‐beam
coupling in photorefractive semiconductors under an external dc field E 0 . This model …

… Moreover, due to the high Q factor and cavity resonance enhancement, the presence of
SPG can be evidently observed in our TFLN microdisk despite the relatively small refractive …

… increase slightly at smaller wavelengths because of resonance enhancement, this would not
affect the … To probe the 2K G grating, we saw that the PR grating was written under the same …
