IEEE International Conference on communications

作者： Zhe Liu Wei Guo Changlin Deng Weisheng Hu He Chen Yanbin Zhao Ming Xia State Key Lab of Advanced Optical Communication Systems and Networks Shanghai Jiao Tong University Shanghai Institute of Satellite Engineering Shanghai China Erisson Research USA

In optical satellite network, the possible optical inter-satellite links (OISLs) candidate for each satellite are usually more than laser communication terminals (LCTs) equipped. This poses the link assignment problem (LAP) of how to assign LCTs of each satellite to establish OISLs with the others. In order to make full use of huge bandwidth provided by LCT, the problem of assigning all satellite LCTs to establish OISLs is modeled as a perfect matching problem in the perfect match model, where a perfect matching is searched over a mixed complete bipartite graph. The regular, random greedy and perfect match model based link assignment schemes are considered. Simulation results show that the average node-to-node distance and LCT utilization of perfect match model based link assignment scheme are better than the regular and random greedy link assignment schemes.

All-optical modulator based on a ferrofluid core metal cladding waveguide chip

引用

Chinese Physics B 2013年第9期22卷 470-473页

作者：韩庆邦殷澄李建汤一彬单鸣雷曹庄琪 Jiangsu Key Laboratory of Power Transmission and Distribution Equipment Technology Hohai University Department of Physics State Key Lab of Advanced Optical Communication Systems and NetworksShanghai Jiao Tong University

We propose a novel optical intensity modulator based on the combination of a symmetrical metal cladding optical waveguide （SMCW） and ferrofluid, where the ferrofluid is sealed in the waveguide to act as a guiding layer. The light matter interaction in the ferrofluid film leads to the formation of a regular nanoparticle pattern, which changes the phase match condition of the ultrahigh order modes in return. When two lasers are incident on the same spot of the waveguide chip, experiments illustrate all-optical modulation of one laser beam by adjusting the intensity of the other laser. A possible theoretical explanation may be due to the optical trapping and Soret effect since the phenomenon is considerable only when the control laser is effectively coupled into the waveguide.

Ultrahigh Resolution Fiber-Optic Quasi-Static Strain Sensors for Geophysical Research

引用

Photonic Sensors 2013年第4期3卷 295-303页

作者： Zuyuan HE Qingwen LIU Tomochika TOKUNAGA State Key Lab of Advanced Optical Communication Systems and Networks Shanghai Jiao Tong University Shanghai200240 China Department of Environment Systems University of Tokyo Chiba 277-8563 Japan

A review of our recent work on ultrahigh resolution optical fiber sensors in the quasi-static region is presented, and their applications in crustal deformation measurement are introduced. Geophysical research such as studies on earthquake and volcano requires monitoring the earth＇s crustal deformation continuously with a strain resolution on the order of nano-strains （ne） in static to low frequency region. optical fiber sensors are very attractive due to their unique advantages such as low cost, small size, and easy deployment. However, the resolution of conventional optical fiber strain sensors is far from satisfactory in the quasi-static domain. In this paper, several types of recently developed fiber-optic sensors with ultrahigh resolution in the quasi-static domain are introduced, including a fiber Bragg grating （FBG） sensor interrogated with a narrow linewidth tunable laser, an FBG based fiber Fabry-Perot interferometer （FFPI） sensor by using a phase modulation technique, and an FFPI sensor with a sideband interrogation technique. Quantificational analyses and field experimental results demonstrated that the FBG sensor can provide nano-order strain resolution. The sub-nano strain resolution was also achieved by the FFPI sensors in laboratory. Above achievements provide the basis to develop powerful fiber-optic tools for geophysical research on crustal deformation monitoring.

We have experimentally demonstrated symmetric 40Gb/s TWDM-PON with long passive reach and high power budget. Directly-modulated lasers (DMLs) are used as both downstream and upstream lasers to reduce the system cost, and optical reshaping filter is used to manage the chirp of the DMLs for all the upstream and downstream channels, enabling long distance transmission without dispersion compensation. The power budget is as high as 43 dB for 100-km passive reach, supporting 64 users. © 2013 IEEE.

Mutual optical format conversion between on-of keying and binary phase-shift keying based on stimulated brillouin scattering

引用

Chinese Optics Letters 2013年第10期11卷 15-17页

作者：张严义理林张涛李正璇胡卫生 State Key Lab of Advanced Optical Communication Systems and Networks Shanghai Jiao Tong University

We propose and experimentally demonstrate mutual optical format conversion between signals characterized as 10-Gb/s nonreturn-to-zero on-of-keying(NRZ-OOK) and NRZ binary phase-shift keying(BPSK) types. The conversion is based on stimulated Brillouin scattering(SBS) in a single-mode optical fber. An OOK signal is converted into a BPSK signal through optical carrier absorption, for which a SBS loss of 30 MHz is used in long-haul transmission. The converted BPSK signal is reverted to an OOK signal with a corresponding SBS gain of 30 MHz for direct detection. The proposed OOK-to-BPSK and BPSK-to-OOK format conversions can be implemented in transmitter and receiver nodes by using a laser source as the Brillouin pump.
