Transmission performance analysis of ROADM using holograms

A complete simulation of the transmission performance for Holographic ROADM (Reconfigurable Optical Add-Drop Multiplexer) designs is Presented in this paper. These devices can address several wavelengths from the input to different output fibers, according to the holograms stored in a SLM (Spatial Light Modulator), where all the output sare equalized in power. All combinations of the input wavelengths are possible at the different output fibers. To simulate the transmission Performance of the EH-ROADM,a software program, from Optiwave, has been used.
