Light-based information processing possesses the potential for beyond-Moore computational architectures and complementing or even replacing traditional approaches such as the von Neumann architecture. However, equivalent to the transistor as a fundamental building block in electrical circuits and chips, photonic circuits require controllable non-linear elements and devices to process data.The student will study the feasibility of co-integrating CMOS-technology based photonic structures such as waveguides, modulators and photonic crystals with 2D-materials to investigate, exploit and enhance the inherently large non-linear properties of 2D-materials for active photonic devices. Starting from theoretical investigations (simulations) of potential device architectures, the student will fabricate and characterize these structures and evaluate their potential as building blocks for optical computing.The research will contribute to further understanding and suitability of photonic structures for novel information processing architectures. In particular, the exponentially growing demand in computing power for artificial intelligence (AI) requires novel neuromorphic hardware architectures, which can potentially be addressed by optical computing.

基于光的信息处理具有超越摩尔计算架构的潜力，可以补充甚至取代冯诺依曼架构等传统方法。然而，相当于晶体管作为电路和芯片的基本构建模块，光子电路需要可控的非线性元件和设备来处理数据。学生将研究共同集成基于 CMOS 技术的光子结构（如波导）的可行性、调制器和带有 2D 材料的光子晶体，用于研究、利用和增强有源光子器件的 2D 材料固有的大非线性特性。从潜在器件架构的理论研究（模拟）开始，学生将制造和表征这些结构，并评估它们作为光学计算构建模块的潜力。该研究将有助于进一步理解光子结构及其对新型信息处理架构的适用性。特别是，人工智能（AI）计算能力呈指数级增长的需求需要新颖的神经形态硬件架构，而光学计算可能可以解决这一问题。
