| 2 | Fabrication of on-chip probes for double-tip scanning tunneling microscopy显示文摘A reduction of the interprobe distance in multiprobe and double-tip scanning tunneling microscopy to the nanometer scale has been a longstanding and technically difficult challenge.Recent multiprobe systems have allowed for significant progress by achieving distances of~30 nm using two individually driven,traditional metal wire tips.For situations where simple alignment and fixed separation can be advantageous,we present the fabrication of on-chip double-tip devices that incorporate two mechanically fixed gold tips with a tip separation of only 35nm.We utilize the excellent mechanical,insulating and dielectric properties of high-quality SiN as a base material to realize easy-to-implement,lithographically defined and mechanically stable tips.With their large contact pads and adjustable footprint,these novel tips can be easily integrated with most existing commercial combined STM/AFM systems. | Maarten Leeuwenhoek Freek Groenewoud Kees van Oosten Tjerk Benschop Milan P.Allan Simon Groblacher | 2020 | Microsystems & Nanoengineering2020，6，1： | 1 |
| 3 | Integrated optical-readout of a high-Q mechanical out-of-plane mode显示文摘The rapid development of high-QM macroscopic mechanical resonators has enabled great advances in optomechanics.Further improvements could allow for quantum-limited or quantum-enhanced applications at ambient temperature.Some of the remaining challenges include the integration of high-QM structures on a chip,while simultaneously achieving large coupling strengths through an optical read-out.Here,we present a versatile fabrication method,which allows us to build fully integrated optomechanical structures.We place a photonic crystal cavity directly above a mechanical resonator with high-QM fundamental out-of-plane mode,separated by a small gap.The highly confined optical field has a large overlap with the mechanical mode,enabling strong optomechanical interaction strengths.Furthermore,we implement a novel photonic crystal design,which allows for a very large cavity photon number,a highly important feature for optomechanical experiments and sensor applications.Our versatile approach is not limited to our particular design but allows for integrating an out-of-plane optical read-out into almost any device layout.Additionally,it can be scaled to large arrays and paves the way to realizing quantum experiments and applications with mechanical resonators based on high-QM out-of-plane modes alike. | Jingkun Guo Simon Groblacher | 2022 | Light(Science & Applications)2022，11，10： | 0 |
| 4 | Recent advances in metasurface design and quantum optics applications with machine learning,physics-informed neural networks,and topology optimization methods显示文摘As a two-dimensional planar material with low depth profile,a metasurface can generate non-classical phase distributions for the transmitted and reflected electromagnetic waves at its interface.Thus,it offers more flexibility to control the wave front.A traditional metasurface design process mainly adopts the forward prediction algorithm,such as Finite Difference Time Domain,combined with manual parameter optimization.However,such methods are time-consuming,and it is difficult to keep the practical meta-atom spectrum being consistent with the ideal one.In addition,since the periodic boundary condition is used in the meta-atom design process,while the aperiodic condition is used in the array simulation,the coupling between neighboring meta-atoms leads to inevitable inaccuracy.In this review,representative intelligent methods for metasurface design are introduced and discussed,including machine learning,physics-information neural network,and topology optimization method.We elaborate on the principle of each approach,analyze their advantages and limitations,and discuss their potential applications.We also summarize recent advances in enabled metasurfaces for quantum optics applications.In short,this paper highlights a promising direction for intelligent metasurface designs and applications for future quantum optics research and serves as an up-to-date reference for researchers in the metasurface and metamaterial fields. | Wenye Ji Jin Chang He-Xiu Xu Jian Rong Gao Simon Groblacher H.Paul Urbach Aurele J.L.Adam | 2023 | Light(Science & Applications)2023，12，8： | 0 |
