The primary objective of INPhO is the design, fabrication and validation of densely integrated nonlinear phononic circuits for parametric information processing at gigahertz frequencies equipped with an optomechanical interface. To this end, we take advantage of a unique experimental hybrid architecture that combines the high operation frequencies of surface acoustic waves (SAWs) and the nonlinear high-quality factor modes of nanomechanical resonators with one of the arguably most advanced optically active nanosystem, i.e. epitaxial semiconductor quantum dots (QDs). INPhO will thus see through the development of a set of numerical and experimental tools allowing for (i) a thorough investigation of nonlinear mechanical resonators interfaced by SAWs and (ii) for an optimization of their optomechanical coupling to QDs, in view of designing tunable nonlinear phononic circuit elements combined with an integrated optical read-out. These nonlinear, on-chip photonic-phononic interconnects integrating programmable elements will be harnessed to push the boundaries of nanomechanical parametric logic to the gigahertz domain. INPhO will build on careful engineering of nonlinear mechanical modal interactions to implement parametric control schemes and demonstrate BIT-flipping, as a first proof-of-concept single-bit logic gate. The final goal of the project lies in the demonstration of the scalability of the proposed architecture through the design and fabrication of multi-resonator phononic circuits. The devices will encompass coupled and programmable nonlinear phononic elements co-integrated with advanced photonic circuitry for opto-mechanical readout. They will illustrate the perspectives opened by the proposed platform to yield mechanical logic-based devices with radiofrequency-to-optical transduction. The implementation of these optomechanically-interfaced nonlinear integrated phononic circuits builds upon the unique combination of the complementary expertise of the French and German partners at Besançon and Münster. The WWU partner masters and contributes the heterointegration of QD heterostructures onto SAW substrates. The FEMTO-ST partner has long-standing matching expertise in the design and fabrication of advanced, yet passive phononic devices to localize and guide SAWs on highly coupled piezoelectric materials. The unique bundling of complementary technological know-hows in INPhO allows for an unprecedented combination of both outstanding phononic and optomechanical properties on a unified platform which are out-of-reach in a monolithic approach. By developing cutting-edge hybrid integrated phononic circuits and devices, INPhO will pave the way towards new paradigms for electronic-photonic-phononic classical information and communication technologies. The INPhO platform, combining nonlinear phononic circuit elements with one of the best solid-state quantum emitter also open far-reaching prospect in the emerging field of hybrid quantum technologies.

INPhO的主要目标是设计，制造和验证密集集成的非线性声子电路，用于在千兆赫兹频率下进行参数信息处理，并配备光机接口。为此，我们利用一个独特的实验混合架构，结合了高工作频率的表面声波（SAW）和非线性高品质因子模式的纳米机械谐振器，可以说是最先进的光学活性纳米系统，即外延半导体量子点（QD）。因此，INPhO将看到一套数值和实验工具的开发，允许（i）对SAW接口的非线性机械谐振器进行彻底的研究，以及（ii）优化其与QD的光机械耦合，以设计可调谐非线性声子电路元件与集成光学读出相结合。这些非线性的、集成了可编程元件的片上光子-声子互连将被用来将纳米机械参数逻辑的边界推向千兆赫域。INPhO将建立在非线性机械模态相互作用的精心工程基础上，以实现参数控制方案，并展示BIT翻转，作为第一个概念验证的单比特逻辑门。该项目的最终目标在于通过多谐振器声子电路的设计和制造来演示所提出的架构的可扩展性。该设备将包括耦合和可编程的非线性声子元件共同集成与先进的光子电路的光机械读出。他们将说明所提出的平台，以产生机械逻辑为基础的设备与射频到光学转换打开的角度。这些光机接口非线性集成声子电路的实现建立在贝桑松和明斯特的法国和德国合作伙伴互补专业知识的独特组合之上。WWU的合作伙伴掌握和贡献的量子点异质结构到SAW基板的异质集成。FEMTO-ST合作伙伴在设计和制造先进但无源的声子器件方面拥有长期的匹配专业知识，可在高度耦合的压电材料上定位和引导SAW。INPhO独特的互补技术诀窍捆绑在一起，可以在一个统一的平台上前所未有地结合出色的声子和光机特性，这在单片方法中是无法实现的。通过开发尖端的混合集成声子电路和器件，INPhO将为电子-光子-声子经典信息和通信技术的新范式铺平道路。INPhO平台将非线性声子电路元件与最好的固态量子发射器之一相结合，在新兴的混合量子技术领域也开辟了深远的前景。
