SOI芯片式高速多通道光衰减器
SOI Chip-based High Speed Multichannel VOA
SOI芯片式高速多通道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.
