项目摘要
Non Technical Abstract:Today, optical technologies are the backbone of our information society, empowering impactful services such as virtual medical consultations, access to data stored in the cloud, and energy-efficient high-performance computing in largescale datacenters. Photonic solutions are particularly suited to enable these services due to the advantages of light such as multi-terabit bandwidths, low-loss propagation over kilometers, and low cross-talk. In fact, some internet provides have begun providing service entirely through light (fiber optics). As a result, the advancement of photonic telecommunications technologies will have a profound impact upon our nation by providing improved performance of internet-based services, reduced energy consumption, and a lower cost of construction/operation for networks. Current photonic modulators, small switches which convert electrical signals into optical pulses, are limited in their speed due to the weak interaction of light and matter. More recently, metals have been utilized to enhance this interaction, facilitating a reduction of device size and increase of speed. Yet, these devices struggle to achieve efficient transmission ~10%, which is simply insufficient for many applications. Here, we look utilize the benefits of both approaches by allowing the lossy metallic nature to be engaged and disengaged when desired. This approach limits the loss of the structure while still maintaining the benefits of metal plasmonic structures. By partnering with existing programs at the home university, the research will provide avenues for local high school students, teachers, and undergraduates to learn about impact of light-based technologies on our society while providing a platform to train a highly skilled workforce. Technical Abstract:Despite significant research in the areas of photonic and plasmonic-based approaches, there is yet to be a device which achieves efficient all-around performance (modulation strength, insertion loss, energy consumption, size, and speed). Photonic approaches suffer from poor light-matter interactions, requiring speed restricting resonators and long interaction lengths, while plasmonic approaches have yet to overcome the large insertion loss associated with their metallic components. This proposal seeks to solve this dilemma through a new design approach in which plasmonic elements are disengaged in the off- (transmissive) state to minimize insertion loss, yet are engaged in the on-state to achieve large modulation in a short distance. This is achieved through a specifically chosen set of oxide layers which appear dielectric to the optical mode under no electrical bias, yet can be modulated into an epsilon-near-zero condition (effectively engaging the plasmonic nature) to achieve efficient modulation through free-carrier accumulation and depletion. It is shown that this approach is able to produce the first modulator design capable of efficient all-around performance: area of 3 square microns, 1.5 dB, 9dB extinction ratio, 12 fJ/bit energy consumption, and 112 GHz bandwidth. Although it is impactful for integrated systems, the approach is general and may also find applications in related areas such as metamaterials and sensors. Additionally, the realization of the device will demonstrate that plasmonic systems are not synonymous with loss and the benefits of such systems (confinement, enhanced light-matter-interaction) can be employed without detrimental loss.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
非技术摘要:今天,光学技术是我们信息社会的支柱,它赋予了有影响力的服务,如虚拟医疗咨询,访问存储在云中的数据,以及大规模数据中心的节能高性能计算。光子解决方案特别适合实现这些服务,因为光具有多太比特带宽、低损耗传播公里数和低串扰等优点。事实上,一些互联网提供商已经开始完全通过光(光纤)提供服务。因此,光子通信技术的进步将对我们的国家产生深远的影响,通过提供更好的基于互联网的服务性能,降低能源消耗,降低网络的建设/运营成本。目前的光子调制器,即将电信号转换为光脉冲的小型开关,由于光和物质的弱相互作用而限制了它们的速度。最近,金属已被用于增强这种相互作用,促进了器件尺寸的减小和速度的增加。然而,这些设备难以实现约10%的有效传输,这对于许多应用来说根本不够。在这里,我们将利用这两种方法的优点,允许有损耗的金属性质在需要时接合和脱离。这种方法限制了结构的损失,同时仍然保持了金属等离子体结构的优点。通过与所在大学的现有项目合作,该研究将为当地高中生、教师和本科生提供途径,了解基于光的技术对我们社会的影响,同时提供一个培养高技能劳动力的平台。技术摘要:尽管在基于光子和等离子体的方法领域进行了大量研究,但还没有一种设备能够实现高效的全方位性能(调制强度,插入损耗,能耗,尺寸和速度)。光子方法遭受较差的光-物质相互作用,需要速度限制谐振器和长的相互作用长度,而等离子体方法尚未克服与其金属组件相关的大插入损耗。该提议试图通过新的设计方法来解决这种困境,其中等离子体激元元件在关闭(透射)状态下脱离以最小化插入损耗,而在开启状态下参与以在短距离内实现大调制。这是通过一组特别选择的氧化物层来实现的,这些氧化物层在没有电偏置的情况下对于光学模式表现为介电的,但可以被调制到ε接近零的条件(有效地接合等离子体性质),以通过自由载流子积累和耗尽来实现有效的调制。它表明,这种方法是能够产生的第一个调制器的设计能够有效的全面的性能:3平方微米,1.5 dB,9dB消光比,12 fJ/位的能量消耗,和112 GHz的带宽。虽然它对集成系统有影响,但这种方法是通用的,也可能在超材料和传感器等相关领域得到应用。此外,该设备的实现将证明等离子体系统不是损失的同义词,这种系统的好处(限制,增强的光物质相互作用)可以在没有有害损失的情况下使用。该奖项反映了NSF的法定使命,并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。
