Abstract ：
The use of metal foil catalysts in the chemical vapor deposition of graphene films makes graphene transfer an ineluctable part of graphene device fabrication, which greatly limits industrialization. Here, an oxide phase-change material (V2O5) is found to have the same catalytic effect on graphene growth as conventional metals. A uniform large-area graphene film can be obtained on a 10 nm V2O5 film. Density functional theory is used to quantitatively analyze the catalytic effect of V2O5. Due to the high resistance property of V2O5 at room temperature, the obtained graphene can be directly used in devices with V2O5 as an intercalation layer. A wafer-scale graphene-V2O5-Si (GVS) Schottky photodetector array is successfully fabricated. When illuminated by a 792 nm laser, the responsivity of the photodetector can reach 266 mA W-1 at 0 V bias and 420 mA W-1 at 2 V. The transfer-free device fabrication process enables high feasibility for industrialization.

Abstract ：
热电堆红外探测器主要是由热电偶为基本单元所构成的一种探测器件,因其原理简单、工作时不需要冷却设备等优势已被广泛应用在生产生活的各个方面.然而,传统热电堆器件所选用材料的吸收率通常处在较低水平,并且大部分与微加工工艺不兼容.在此,本文设计提出了一种带有垂直石墨烯(vertical graphene,VG)的金属热电堆红外探测器.通过等离子体增强化学气相沉积(plasma enhanced chemical vapor deposition,PECVD)生长VG并将其保留在器件的热结处,从而实现热电堆红外探测器的宽带和高响应特性.这种复合结构的探测器在波长792 nm的情况下,室温响应率最高可达1.53 V/W,与没有VG的热电堆红外探测器相比,前后响应结果可增加28倍左右,响应时间缩短至0.8 ms左右.该制备过程与微加工工艺相兼容,同时整体提升了器件性能,并适合于大规模生产.此外,利用表面等离激元共振的原理将VG与金属纳米颗粒相互结合,发现在前后同等条件下材料的光吸收有明显的增强,所产生的热电势响应最高可增6倍.以上结果表明,VG在多种应用中具有巨大的潜力,包括光电检测、微发电装置等,该技术为制备高性能热电堆红外探测器和其他传感器件提供了一种新的途径.

Abstract ：
Direct chemical vapor deposition of graphene on semiconductors and insulators provides high feasibility for integration of graphene devices and semiconductor electronics. However, the current methods typically rely on high temperatures (>1000 degrees C), which can damage the substrates. Here, a growth method for high-quality large-area graphene at 300 degrees C is introduced. A multizone furnace with gradient temperature control was designed according to a computational fluid dynamics model. The crucial roles of the chamber pressure in the film continuity and hydrogen composition in the graphene defect density at low temperature were revealed. As a result, a uniform graphene film with the Raman ratio ID/IG = 0.08 was obtained. Furthermore, a technique of laminating single-crystal Cu foil as a sacrificial layer on the substrate was proposed to realize transfer-free growth, and a wafer-scale graphene transistor array was demonstrated with good performance consistency, which paves the way for mass fabrication of graphene devices.

Abstract ：
The work introduces a localized surface plasmon resonance (LSPR) sensor chip integrated with vertical-cavity surface-emitting lasers (VCSELs). Using VCSEL as the light source, the hexagonal gold nanoparticle array was integrated with anodic aluminum oxide (AAO) as the mask on the light-emitting end face. The sensitivity sensing test of the refractive index solution was realized, combined with microfluidic technology. At the same time, the finite-difference time- domain (FDTD) algorithm was applied to model and simulate the gold nanostructures. The experimental results showed that the output power of the sensor was related to the refractive index of the sucrose solution. The maximum sensitivity of the sensor was 1.65 x 10(6) nW/RIU, which gives it great application potential in the field of biomolecular detection.

Abstract ：
Surface plasmon resonance (SPR) of metal nanostructures has broad application prospects in the fields of sensing, energy, catalysis and optics. This paper reports a graphene-assisted method for preparing large-scale single-crystal Ag(111) nanoparticle (NP) arrays based on the ion implantation technique. By surface periodic patterning treatment and annealing of the implanted sample, regularly arranged Ag NPs can be prepared on the sample surface. A new application for graphene is proposed, that is, as a perfect barrier layer to prevent metal atoms from evaporating or diffusing. All the Ag NPs show (111) crystal orientation. Besides, the Ag atoms are covered by graphene immediately when they precipitate from the substrate, which can prevent them from being oxidized. On the basis of this structure, as one of the applications of the metal SPR, we have measured the surface-enhanced Raman scattering effect and found that the G peak of the Raman spectrum of the graphene achieved about 20 times enhancement.

Abstract ：
We investigated the frequency noise coupling mechanism of a 2 μm polarizationmaintaining single frequency fiber laser (SFFL) theoretically and experimentally. The coupling of pump's relative intensity noise (RIN) to frequency noise of a single-frequency high-gain silica fiber laser is shown experimentally to be consistent with a theoretical model where thermal expansion and thermo-optic effect mediate the coupling. The measured and theoretical frequency noise of the 2 μm SFFL with three pump sources is compared. We find using a 1550 nm single frequency laser pump source produces the lowest frequency noise, less than 100 Hz/ √Hz at frequencies higher than 100 Hz. © 2021 Optical Society of America.

Abstract ：
Metasurfaces offer complete control of optical wavefront at the subwavelength scale, advancing a new class of artificial planar optics, including lenses, waveplates, and holograms, with unprecedented merits over conventional optical components. In particular, the ultrathin, flat, and compact characteristics of metasurfaces facilitate their integration with semiconductor devices for the development of miniaturized and multifunctional optoelectronic systems. In this work, generation of structured light is implemented at an ultracompact wafer-level through the monolithic integration of metasurface with standard vertical cavity surface-emitting lasers (VCSELs). This work opens new perspectives for the design of structured light systems with compactness, lightweight, and scalability. Ultracompact beam structured laser chips with versatile functionalities are experimentally demonstrated, including multichannel beams array generation, on-chip large-angle beam steering up to 60 degrees, and wafer-level holographic beam shaping with a wide field of view (about 124 degrees). The results will promote the development of compact light structuring systems with great potential in 3D imaging, displays, robotic vision, human-computer interaction, and augmented/virtual reality.

Abstract ：
Vertical-cavity surface-emitting lasers (VCSELs) play a key role in the development of the next generation of optoelectronic technologies, thanks to their unique characteristics, such as low-power consumption, circular beam profile, high modulation speed, and large-scale twodimensional array. Dynamic phase manipulation of VCSELs within a compact system is highly desired for a large variety of applications. In this work, we incorporate the emerging microfluidic technologies into the conventional VCSELs through a monolithic integration approach, enabling dynamic phase control of lasing emissions with low power consumption and low thermal generation. As a proof of concept, a beam steering device is experimentally demonstrated by integrating microfluidic channel on a coherently coupled VCSELs array. Experimental results show that the deflection angles of the laser beam from the chip can be tuned from 0 to 2.41 under the injection of liquids with different refractive index into the microchannel. This work opens an entirely new solution to implement a compact laser system with real-Time wavefront controllability. It holds great potentials in various applications, including optical fiber communications, laser printing, optical sensing, directional displays, ultra-compact light detection and ranging (LiDAR). © 2021 OSA - The Optical Society.
