4/spl times/4 high-speed switching subsystem with VOA (< 10 /spl mu/s) using PLZT beam-deflector for optical burst switching

摘要

We developed a 4/spl times/4 high-speed optical switch subsystem with variable optical attenuation (VOA). This switch subsystem allows high-speed level adjustment as well as high-speed switching by using the electro-optic (EO) effect of PLZT. We demonstrate 5.5-/spl mu/s switching with VOA to obtain the desired output power for optical burst switching (OBS).
