International Conference on Optical Communications and Networks, 2017Co-Authors: Yifan Zhao, Jian WangAbstract:We experimentally demonstrate visible-light co ding/de co ding utilizing Hexadecimal vector beam array for parallel communication link. The Hexadecimal base mode is investigated and 128-ary is also available. We present vector beam array carrying 4×6/6×8/12×16 Hexadecimal numbers and error-free data stream transmission performance is also demonstrated.

high base vector beam encoding decoding for visible light communications
Optics Letters, 2015Co-Authors: Yifan Zhao, Jian WangAbstract:Polarization is a basic property of light. Different from well-known linear, circular, and elliptical polarizations, which are spatially homogeneous, a vector light beam with spatially variant polarization states has received increasing interest for its expanded functionalities. In this Letter, we present a visible-light communication link exploiting high-base vector beam encoding/decoding. Using a single phase-only spatial light modulator, we generate 16 states of vector beams representing Hexadecimal numbers. In the visible-light communication link experiment, we transmit a random high-base number sequence with 10,000 Hexadecimal numbers and a 64×64 pixel Lena gray image with 8192 Hexadecimal numbers. The bit error rate is evaluated, and zero error among all received Hexadecimal numbers is achieved, showing favorable link communication performance using the high-base vector beam encoding/decoding.

silicon organic hybrid slot waveguide based three input multicasted optical Hexadecimal addition subtraction
Scientific Reports, 2015Co-Authors: Chengcheng Gui, Jian WangAbstract:By exploiting multiple non-degenerate four-wave mixing in a silicon-organic hybrid slot waveguide and 16-ary phase-shift keying signals, we propose and simulate three-input (A, B, C) multicasted 40-Gbaud (160-Gbit/s) optical Hexadecimal addition/subtraction (A + B − C, A + C − B, B + C − A, A + B + C, A − B − C, B − A − C). The error vector magnitude (EVM) and dynamic range of signal power are analyzed to evaluate the performance of optical Hexadecimal addition/subtraction.

optical Hexadecimal coding decoding using 16 qam signal and fwm in hnlfs
Journal of Lightwave Technology, 2012Co-Authors: Jian Wang, Jengyuan Yang, Alan E WillnerAbstract:We propose a simple approach to manipulating the constellation of a multilevel modulation signal in the optical domain. By exploiting degenerate four-wave mixing (FWM) in highly nonlinear fibers and adopting 16-ary quadrature amplitude modulation (16-QAM) signal, we demonstrate 10-Gbaud/s optical variable symbol-wise Hexadecimal coding/decoding assisted by a continuous-wave (CW) pump or a phase-modulated pump. The former takes the coding through the phase conjugation of degenerate FWM, and the latter offers enhanced coding via the combined contributions from the phase modulation of the pump and the phase-conjugated FWM. The penalty of optical signal-to-noise ratio for coding/decoding is measured to be ${ dB with a CW pump and ${ dB with a $(0, \pi/4)$ phase-modulated pump at a bit-error rate of 2e-3 (enhanced forward error correction threshold). The dependence of coding/decoding performance on the phase modulation depth of the pump and the signal/pump misalignment is also investigated. Moreover, considering that a Hexadecimal number denotes four binary numbers, we develop the symbol-wise Hexadecimal coding/decoding to general binary coding/decoding, i.e., 10-Gbaud/s symbol-wise Hexadecimal coding/decoding is accompanied by 40-Gbit/s binary coding/ decoding.

a rotation algorithm for multiple layer images by a Hexadecimal grid graph model
International Conference on Industrial Technology, 2016Co-Authors: Koichi Anada, Takeo Yaku, Taikoh Ikeda, Ken YokotaAbstract:We deal with data structures and algorithms for bundles of binary images represented by raster data. In this paper, a bundle with images is called a multiple layer image. Our purpose is to introduce algorithms for rotation of objects included in multiple layer binary images. In addition, we will provide both of rotation and translation in a binary image at the same time.

2011 IEEE Symposium on Visual Languages and Human-Centric Computing (VL HCC), 2011Co-Authors: Shinji Koka, Kenshi Nomaki, Koichi Anada, Takeo YakuAbstract:We discuss tabular forms. It is known in the previous studies that the “octgrid” is a data structure for single layer tabular forms with ruled line preserving algorithms. And the “hexadeci-grid” is known as a data structure for multiply layered tabular forms which is a generalization of the “octgrid”. Our purpose of this paper is to propose a new algorithm based on the “hexadeci-grid” model for editing tabular forms.
