Improved modulation format identification based on Stokes parameters using combination of fuzzy c-means and hierarchical clustering in coherent optical communication system被引量：2
《Chinese Optics Letters》2015年第10期35-39,共5页程龙雪 席丽霞 赵东鹤 唐先锋 张文博 张晓光 
supported by the National Natural Science Foundation of China under Grant No. 61205065
In this Letter, we develop the Stokes space-based method for modulation format identification by combing power spectral density and a cluster analysis to identify quadrature amplitude modulation（QAM） and phase-shift...

Coupled-mode analysis for single-helix chiral fiber gratings with small core-offset被引量：2
《Chinese Optics Letters》2011年第7期17-20,共4页杨利 薛林林 苏觉 钱景仁 
supported by the National Natural Science Foundation of China (No. 60807023);the Fundamental Research Funds for the Central Universities;the Scientific Research Foundation for the Returned Overseas Chinese Scholars;the State Education Ministry;the Anhui Key Laboratory of Optoelectronic Science and Technology
Using conventional coupled-mode theory, a set of coupled-mode equations are formulated for single-helix chiral fiber long-period gratings. A helical-core fiber is analyzed as an example. The analysis is simple in math...

Offset quantum-well method for tunable distributed Bragg reflector lasers and electro-absorption modulated distributed feedback lasers
《Chinese Optics Letters》2005年第8期455-456,共2页阚强 丁颖 赵玲娟 朱洪亮 周帆 王鲁峰 王宝军 王圩 
This work was supported by the National "863" Pro-gram of China under Grant No. 2002AA312150 and2001AA312050
A two-section offset quantum-well structure tunable laser with a tuning range of 7 nm was fabricated using offset quantum-well inethod. The distributed Bragg reflector （DBR） was realized just by selectively wet etch...
