SOI芯片光電探測器陣列
SOI Chip-based Photodetector Array
SOI芯片式光電探測器陣列，該產品基于硅基鍺-硅光電探測器，實現了多通道光電探測器的單片化集成，可片上集成光學混頻器，芯片尺寸小，集成度高，偏振相關性小，模擬帶寬大，可提供裸片或光電一體化封裝產品方案。
Chip-based multi-channel photodetector array is a product based on Ge-Si SOI platform. This product achieved the integration of multi-channel photodetectors on a single SOI chip. The MMI-based optical hybrider/mixer could also be integrated on the chip. It is capable of tiny polarization sensitivity and large electrical bandwidth. Both the die products and chip package solutions are provided.
