Digital Photonics -Paradigm Shift in Optoelectronics

为了将光电子学从模拟技术领域转向数字技术领域，我们研究和开发了全光逻辑门器件、全光触发器器件、大规模光开关电路、非互易偏振控制光学器件和光缓存集成电路。基于这些元件，我们展示了数字光子集成电路的原型。还研究了用于制造这些光子器件和电路的集成工艺技术。

In order to shift the optoelectronics from the analog to the digital technology domain, we have studied and developed all optical logic gate devices, all optical flip-flop devices, large scale optical switch circuits, non-reciprocal and polarization controlling optical devices, and optical buffer memory integrated circuits. Based on these components, we demonstrated prototypes of digital photonic integrated circuits. Integration process technologies for fabricating these photonic devices and circuits have also been investigated.
