MEMS-based optical equalizer manages gain without pain

摘要

As our technology pushes further toward all-optical networks with a minimum of inline electronics, MEMS (micro-electromechani-cal-system)devices are playing key roles in optical-signal processing. One such device, the Model 2200 dynamic gain equalizer from the Silicon Light Machines subsidiary of Cypress Semiconductor, simplifies maintaining signal-strength flatness over the bandwidth of the numerous wavelengths of a DWDM (dense-wavelength-divkion-multiplexing) system.
