  • Numerical analysis of O-PCF structure for sensing applications with high relative sensitivity 

    Ahmed, Kawsar; Asaduzzaman, Sayed; Arif, Md. Faizul Huq (IEEE Xplore, 2016-01-28)
    In this study, micro structured core and cladding based O-PCF has been analyzed by its propagation characteristics. The effects of pitch variation, total power consumption and effective refractive index are investigated ...
  • Porous core Photonic Crystal Fiber based chemical sensor 

    Paul, Bikash Kumar; Islam, Md. Shadidul; Chowdhury, Sawrab; Asaduzzaman, Sayed; Ahmed, Kawsar (IEEE Xplore, 2017-02-16)
    In this paper, a porous core photonic crystal fiber based chemical sensor has been proposed. The cladding of the proposed PCF is hybrid where inner three layers are hexagonal and the outer two layers are circular. The ...
  • Proposal of simple gas sensor based on micro structure optical fiber 

    Morshed, Monir; Asaduzzaman, Sayed; Arif, Md. Faizul Huq; Ahmed, Kawsar (IEEE Xplore, 2015-10-29)
    This paper presents a simple structure of photonic crystal fiber (PCF) based gas sensors. Gas sensors can be used in gas production facilities for safe measurement. The index guiding properties of two rings circular PCF ...
  • Simulation based analysis of formalin detection through photonic crystal fiber 

    Arif, Md. Faizul Huq; Biddut, Md. Jaminul Haque; Ahmed, Kawsar; Asaduzzaman, Sayed (IEEE Xplore, 2016-12-01)
    Formalin is a dangerous organic chemical substance in today's life. It is the solution of two substances; Formaldehyde and Water. Formalin is used forlong time preservation for various types of foods and other things from ...
  • Spiral photonic crystal fiber for gas sensing application 

    Islam, Md. Ibadul; Khatun, Maksuda; Sen, Shuvo; Ahmed, Kawsar; Asaduzzaman, Sayed (IEEE Xplore, 2017-02-16)
    This paper proposes, the design and characterization of a spiral shape photonic crystal fiber for gas sensing application. The core region of the proposed PCF is oriented with elliptical air holes in a hexagonal shape and ...
