Abstract:

Data retrieval are an important information processing task. In optical information processing, the usual method is spatial filtering based on Fourier optics. However, these methods are very difficult to implement in practical applications. In recent years, random lasers due to its cavity free property have attracted widespread attention, but few applications have been reported. Here, we develop an information retrieval method based on random lasers, where the spatial frequency spectrum of a contaminated Fourier transform hologram can be obtained by detecting the temporal frequency spectrum information from random lasing. The hologram information can be reconstructed from an inverse Fourier transform of the spatial frequency spectrum obtained after data processing. This method may potentially find applications in information optics and optical data storage. (C) 2015 AIP Publishing LLC.
