Optical router based on a phase-coding multiplexed collinear holographic storage system

This paper analyzes the distribution characteristics of crosstalk in a phase-coded multiplexed collinear holographic storage system and realizes an optical router by this characteristic. The system employs collinear holographic storage technology to cache the signals of the optical router in the holographic storage material. Different routing addresses are represented by the phase code. The system reads the signals in the holographic storage material and accomplishes the routing function. The benefit of this approach is that it minimizes the loss of optical signal and possesses robust anti-interference capability, offering an efficient solution in the development of optical routing.
