Simulation of transmission performance for equalized holographic ROADM designs

摘要

A complete simulation of the transmission performance for Equalized Holographic ROADM(Reconfigurable Optical Add‐Drop Multiplexer) designs is presented in this paper. These devices canaddress several wavelengths from the input to different output fibres, according to the hologramsstored in a SLM (Spatial Light Modulator), where all the outputs are equalized in power. Allcombinations of the input wavelengths are possible at the different output fibres. To simulate thetransmission performance of the EH‐ROADM, a software program, from Optiwave, has been used.The correspondence between physical blocks of the device (grating, SLM, lens…) and those simulatedin the program (filters, losses, splitters…) has been defined in order to obtain a close agreementbetween the theoretical transmission performance and the simulated one. To complete the reviewabout equalized holographic ROADMs some guidelines about its design have been done.
