Abstract We have investigated the photodiffractive effect induced by resonant excitations in semiconductor microstructures by means of the multiple wave coupling method. We have derived set of multiple wave coupling equations for photodiffractions in the case of coexistence of refraction and absorption gratings. Numerical results of the equations for a few typical cases have been analysed in detail, and their physical significance is also discussed.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
