1 微纳尺度光与物质相互作用 Micro/Nano-scale Light–Matter Interactions
探索微纳尺度下光与物质相互作用的物理机制，涵盖光镊、光热效应与光声效应等多种形式。 基于倏逝场的偏振梯度力、螺旋度梯度力、光泳力与光辐射压力的协同效应， 可实现粒子的精准捕获、定向输运与非接触操控。 相关研究揭示了微纤-微腔系统中的偏振相关力与力矩共振机制， 以及干燥环境中光热驱动微机械臂的新效应，为片上光驱动系统奠定物理基础。 We explore the physical mechanisms of light–matter interactions at the micro/nano scale, encompassing optical trapping, photothermal effects, and photoacoustic phenomena. By leveraging synergetic optical forces, including polarization/helicity gradient forces, photophoretic forces, and radiation pressure in evanescent fields, we demonstrate precision particle capture, directed transport, and non-contact manipulation. Key discoveries include polarization-dependent forces and torques at resonance in microfiber–microcavity systems, and opto-thermo-mechanical actuation in the dry adhesive regime.

Integration with microfluidic systems provides a compact platform for bio-detection, single-molecule sensing, and nanoparticle sorting. This work demonstrated the first lens-free on-chip optical tweezers using metasurface freeform optics integrated with planar waveguides.
3 集成光芯片 Integrated Photonic Chips
原创提出级联模式转换干涉仪（CMI）结构：通过在单个波导中引入模式选择性耦合， 使光场在不同横向模式之间依序转换，产生等效的多轨道干涉效应。 这一架构可同时且独立地调控谱形状（滤波器线型）、自由谱范围（FSR）与时域波形， 并在单环谐振器中实现多模光子分子效应。 同时发展了基于多模滤波的片上拉曼噪声抑制技术， 相关器件覆盖SOI、氮化硅、铌酸锂薄膜等主流光子集成平台， 为下一代光通信、激光雷达与量子光学提供新型片上解决方案。 We introduced cascaded-mode conversion interferometers (CMIs): by engineering mode-selective coupling within a single waveguide, light sequentially transfers between transverse modes, producing effective multi-path interference. This architecture achieves simultaneous and independent control of spectral shape (filter lineshape), free spectral range (FSR), and temporal waveform, and reveals multimode photonic molecule effects in a single ring resonator. We also developed on-chip Raman noise suppression via multimode spectral filtering. Devices span SOI, silicon nitride, and thin-film lithium niobate platforms, providing new on-chip solutions for optical communications, LiDAR, and quantum optics.

将电光材料（铌酸锂等）与超表面纳米谐振器耦合，通过外加电场动态调控谐振器的相位响应， 实现超高速、可编程的波前调控。相较于传统液晶或MEMS空间光调制器， 电光超表面在调制带宽（GHz量级）和集成度方面具有显著优势。 探索集成光驱系统在高带宽自由空间光通信、高分辨率固态LiDAR与量子信息处理中的应用前景。 By coupling electro-optic materials (LiNbO₃, etc.) with metasurface nano-resonators, external electric fields dynamically tune the phase response of individual resonators, enabling ultrafast programmable wavefront control. Compared with conventional liquid crystal or MEMS spatial light modulators, electro-optic metasurfaces offer substantial advantages in modulation bandwidth (GHz-scale) and integration density. We target applications in high-bandwidth free-space optical communications, high-resolution solid-state LiDAR, and quantum information processing.
