| 2 | Integrating planar photonics for multi-beam generation and atomic clock packaging on chip显示文摘The commercialization of atomic technologies requires replacing laboratory-scale laser setups with compact and manufacturable optical platforms.Complex arrangements of free-space beams can be generated on chip through a combination of integrated photonics and metasurface optics.In this work,we combine these two technologies using flip-chip bonding and demonstrate an integrated optical architecture for realizing a compact strontium atomic clock.Our planar design includes twelve beams in two co-aligned magneto-optical traps.These beams are directed above the chip to intersect at a central location with diameters as large as 1 cm.Our design also includes two co-propagating beams at lattice and clock wavelengths.These beams emit collinearly and vertically to probe the center of the magneto-optical trap,where they will have diameters of≈100μm.With these devices we demonstrate that our integrated photonic platform is scalable to an arbitrary number of beams,each with different wavelengths,geometries,and polarizations. | Chad Ropp Wenqi Zhu Alexander Yulaev Daron Westly Gregory Simelgor Akash Rakholia William Lunden Dan Sheredy Martin MBoyd Scott Papp Amit Agrawal Vladimir Aksyuk | 2023 | Light(Science & Applications)2023，12，4： | 0 |
| 3 | Tantalum pentoxide:a new material platform for high-performance dielectric metasurface optics in the ultraviolet and visible region显示文摘Dielectric metasurfaces,composed of planar arrays of subwavelength dielectric structures that collectively mimic the operation of conventional bulk optical elements,have revolutionized the field of optics by their potential in constructing high-efficiency and multi-functional optoelectronic systems on chip.The performance of a dielectric metasurface is largely determined by its constituent material,which is highly desired to have a high refractive index,low optical loss and wide bandgap,and at the same time,be fabrication friendly.Here,we present a new material platform based on tantalum pentoxide(Ta2O5)for implementing high-performance dielectric metasurface optics over the ultraviolet and visible spectral region.This wide-bandgap dielectric,exhibiting a high refractive index exceeding 2.1 and negligible extinction coefficient across a broad spectrum,can be easily deposited over large areas with good quality using straightforward physical vapor deposition,and patterned into high-aspect-ratio subwavelength nanostructures through commonly-available fluorine-gas-based reactive ion etching.We implement a series of highefficiency ultraviolet and visible metasurfaces with representative light-field modulation functionalities including polarization-independent high-numerical-aperture lensing,spin-selective hologram projection,and vivid structural color generation,and the devices exhibit operational efficiencies up to 80%.Our work overcomes limitations faced by scalability of commonly-employed metasurface dielectrics and their operation into the visible and ultraviolet spectral range,and provides a novel route towards realization of high-performance,robust and foundry-manufacturable metasurface optics. | Cheng Zhang Lu Chen Zhelin Lin Junyeob Song Danyan Wang Moxin Li Okan Koksal Zi Wang Grisha Spektor David Carlson Henri J.Lezec Wenqi Zhu Scott Papp Amit Agrawal | 2024 | Light(Science & Applications)2024，13，1： | 0 |
