About OGC 2018

The big leaps in optoelectronic technology and academia have drawn increasing attention from the industry community which is always in searching of innovative solutions. The Optoelectronics Global Conference (OGC) was created to pave the way connecting optoelectronic academia and industry as well as connecting China and the rest of the world.

2018 the 3rd Optoelectronics Global Conference will be held concurrently with the

20th China International Optoelectronic Exposition (CIOE) in Shenzhen. The conference aims to promote interaction and exchange of various disciplines among professionals in academia and industry at home and abroad. In addition, it also serves to turn technologies into industrial applications. It’s expected that 300-500 professionals will attend the conference.

OGC will be an ideal platform for scholars, researchers and professionals to exchange insights and discuss the development of optoelectronics industry. It will be a perfect gathering to learn about new perspectives, technologies and trends which might pushes the boundaries of the technology and eventually creates a broader future for optoelectronics applications.

8 symposia will be talked on the conference with the topics covering precision optics, optical communications, lasers, infrared applications, and fiber sensors. Welcome the professionals, experts, managements and students from the universities, research institutions, military enterprises, and optoelectronic companies to attend the conference.

Abstract ― Development of precision robust than the line counterpart since the nanoantenna technology for fluorescence emitter is generally randomly oriented in the enhancement is attractive for a variety of real situation. On top of that, the defocus applications like photodetection, imaging calculation has shown that the nano-imaging and super bright single-photon cross-nanoantenna is able to preserve the source. These emergent applications challenge polarization of the emitter. For a particular the capability of nanoantenna to manipulate emitter orientation, the resultant the fluorescence emitter at multi-dimensional defocus-imaging pattern with the levels, including intensity, polarization, and cross-nanoantenna is very similar to that of a directivity, etc. Previous literatures mainly free emitter, whereas the polarization focus on the intensity enhancement and information is generally lost in the line directivity control because these figures of configuration. Our results indicate that the merits are more visible in the experiment. cross nanoantenna can be widely used as a However, little attention has been paid to the tool for generating giant fluorescence polarization of the emitter, albeit it is enhancement as well as preserving the particularly important for applications such as polarization of emission light, which would be protein detection on cell membrane. Here, we beneficial in the biological diagnosis and cell use a highly symmetrical cross nanoantenna to tracking. enhance the fluorescence intensity while preserving the polarization of the emitter. The cross nanoantenna is made of Au, and fabricated on ITO substrate using electron beam lithography (EBL) technology. The fluorescence emitter is assumed to locate at the middle of gap. The geometry (e.g. arm length, width, gap etc.) of the cross nanoantenna is properly designed to achieve the best balance between the fluorescence excitation rate  and quantum yield q , so exc as to maximize the fluorescence enhancement

Our preliminary results show that the cross configuration is able to generate consistent fluorescence enhancement 30-50 times for emitters with arbitrary polarizations illuminated by a circular polarized light, whereas the line nanoantenna can only provide a maximum 25 times enhancement at a particular polarization that the emitter aligns parallel to the axis of the line. This proves that the cross nanoantenna is practically more

This technique works studies because of its wide applications in the on the principle of exploiting near field, which field of information and telecommunication has already been used for GaAsN, and technologies, security, energy conservation reported. and environment. In particular, a large band-gap shrinkage even by 1-2% nitrogen shows how impactful and practical devices it can bring to the world of physics and engineering by changing the basic structural and electronic properties of the sample. In our technique, we used a focused laser beam to laser anneal a hydrogenated 5nm nm (In0.21Ga0.79)(As0.975N0.025) QW/GaAs SQW and then characterizing it using micro-photoluminescence (μPL) which helps us to study the electronic activity of N- and H-atoms in (InGa)(AsN)/GaAs SQW, and thus the band-gap energy of (InGa)(AsN). But, as shown in figure.1, this technique has a limitation that it burns out the sample for a high power of 35mW, which is in agreement with the theoretical simulation (figure.2) which shows that temperature reaches about 600°C for 35mW at which arsenic (As) desorption takes place. This process leads to laser damage the sample. But, the visible effects start to occur at much lower power i.e., around 15mW. Because of this drawback, we started using a technique called SNOM (Near-field scanning optical microscopy) in which a dielectric tip is used to focus the laser passing through optical fiber on the sample. This technique has many advantages over laser annealing: (1). Quantum dots formed are more confined (diameter of QDs are about 150-200nm with respect to 500nm formed using objective lens). (2).

This extremely high resolution imaging Although the mentioned methods can break circumvented the problem of the ‘diffraction the spatial resolution limit, they still limited limit’ allowed molecular biologists to track by time resolution. Even if SIM is applied to the significant signaling events within obtain superresolution image which has fastest individual cells. Among this various reconstruction speed, at least 9 original super-resolution imaging technologies, low-resolution images need to be captured. In localization microscopy achieve the highest this paper, we propose a novel superresolution resolution, even for individual molecules. But method which aims to reach high live cell imaging remains a challenge for temporal-spatial resolution. Firstly, we localization-based super-resolution imaging deduced the equivalent relationship between because of sparse molecules snapshot is two calculation processes of superresolution required to resolve distinguish between image, PSF and patterns.

Among all of optimization recovery. To address this the malfunctions, pantograph offset is a strong problem, we have developed a noise-corrected reflection of the state. We have proposed a algorithm based on principal component new approach to reconstructing the analysis (NC-PCA) couple with K-factor three-dimensional (3D) information of the image factorization algorithm for raw data bow by substituting the offset with connection prior to CSSTORM localization. In short, of left and right horns. To locate the region of NC-PCA was designed to project time series pantograph horn, we refer to an efficient deep fluorescence image containing many pixels learning method, named Single Shot MultiBox onto a subspace of reduced dimensionality to Detector (SSD). In the located area, region preserve the maximal variability contained in growing or wiener filtering is applied to the data yet optimally reducing the noise. This extract connected components and enhance noise follows the Poisson-distributed the prospects.
