SOI芯片式高速多通道光衰减器
SOI Chip-based High Speed Multichannel VOA
SOI芯片式多通通可调光衰减器，基于硅基载流子色散效应实现高速响应的可调光路衰减，实现多通道VOA器件单片化集成，芯片与多通道光纤阵列和外围驱动电路一体化光电封装，数字化驱动，偏振相关性小，衰减范围大，调节精度高，衰减值稳定，响应时间为纳秒级，可在高速、低时延系统中应用。
Multi-channel variable optical attenuators based on SOI platform is a new product, which is digitally driven to adjust the attenuation of multi-channel fiber optical paths. This product achieved the integration of a large number of VOA channels on a single SOI chip, and electro-optically co-packaged with fiber array and circuit board. It is capable of tiny polarization-sensitivity, large attenuation range, high adjustment accuracy, stable attenuation value, and especially high-speed response time on the order of nano-second. It is of great value for applications in some high-speed and low-time delay system.
