硅基单片集成 7bit 可调光延时器芯片

Single-chip Integrated 7 Bit Optical Delay Chip

〖简介Introduction〗

梓冠光电的单片集成多比特光延时芯片是基于厚膜 SOI 硅光子技术、将硅基光开关和硅波导延时路单片集成的自主研发产品。集成的硅基光开关使其延时态切换速度达到 1 μs 以下,硅波导延时使其延时精度提升 1 个量级,厚膜 SOI 硅光技术使其光损耗达到工程应用水平,单片集成的芯片解决了传统光延时器的体积大、可靠性差问题,是可全方面满足光控相控阵应用要求的新一代产品。

The single-chip integrated multi-bit optical delay chip of Ziguan Photonics is an independently developed product based on thick film SOI silicon photonics technology, which integrates silicon based optical switches and silicon waveguide delay circuits on a single chip. The integrated silicon based optical switch achieves the delay state switching speed less than 1 μs, the delay of silicon waveguide improves its delay accuracy by one order of magnitude, and the thick film SOI silicon optical technology enables the optical loss to reach the level of engineering application. The single chip integrated chip solves the problems of large volume and poor reliability of traditional optical delay devices, and is a new generation product that can fully meet the application requirements of optically contronlled phased array.
