ABSTRACT:A complete simulation of the transmission performance for Equalized 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 fibres, according to the holograms stored in a SLM (Spatial Light Modulator), where all the outputs are equalized in power. All combinations of the input wavelengths are possible at the different output fibres. To simulate the transmission 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 simulated in the program (filters, losses, splitters…) has been defined in order to obtain a close agreement between the theoretical transmission performance and the simulated one. To complete the review about equalized holographic ROADMs some guidelines about its design have been done. RESUMEN:En este artículo se presenta una simulación del funcionamiento en transmisión para diseños de ROADMs (Reconfigurable Optical Add-Drop Multiplexer) Holográficos Ecualizados. Estos dispositivos pueden direccionar varias longitudes de onda de las fibras de entrada a fibras de salida diferentes, según los hologramas almacenados en un SLM (Modulador Espacial de Luz) presentando, además, la potencia de salida ecualizada. Para simular el funcionamiento en transmisión del EH-ROADM, se ha utilizado un programa de software, del fabricante Optiwave, particularizado para nuestra aplicación. La correspondencia entre los bloques físicos del dispositivo (la red de difracción, el SLM, la lente,..) y aquellos simulados en el programa (filtros, pérdidas, divisores de potencia,..) se ha definido para obtener una concordancia ajustada entre el funcionamiento en transmisión teórico y el simulado. También se han incluido en el artículo algunas indicaciones sobre el diseño de ROADMs Holográficos Ecualizados, con el objeto de completar la simulación.

“…The power consumption of PLC-VOA reported in the former paper was mostly greater than 200 mW. [11,13] But in ROADM [14] and multi-channel V-AWG, [15] it is required that the power consumption of the VOA should be less than 150 mW. Although the VOA based on SOI has a very low power consumption, it has a larger coupling loss when coupled with an optical fiber.…”

The power consumption of a variable optical attenuator (VOA) array based on a silica planar lightwave circuit was investigated. The thermal field profile of the device was optimized using the finite-element analysis. The simulation results showed that the power consumption reduces as the depth of the heat-insulating grooves is deeper, the up-cladding is thinner, the down-cladding is thicker, and the width of the cladding ridge is narrower. The materials component and thickness of the electrodes were also optimized to guarantee the driving voltage under 5 V. The power consumption was successfully reduced to as low as 155 mW at an attenuation of 30 dB in the experiment.
