  • A comparative analysis of two different PCF structures for gas sensing application 
    Arif, Md. Faizul Huq; Ahmed, Kawsar; Asaduzzaman, Sayed (IEEE Xplore, 2016-07-11)
    Toxic or Flammable gases and leakage of the gas lines can be detected by photonic crystal fibers for avoiding pollution, explosion or fire. Two different structures of hollow core based Photonic crystal fiber (HC-PCF) has ...
  • High sensitive PCF based chemical sensor for ethanol detection 
    Arif, Md. Faizul Huq; Asaduzzaman, Sayed; Ahmed, Kawsar; Morshed, Monir (IEEE Xplore, 2016-12-01)
    In this paper, a high sensitive photonic crystal fiber structure has been presented for ethanol sensing. Optical properties of the guided mode have been analyzed using full vectorial finite element method. We have investigated ...
  • 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 ...
  • Proposal of a simple structure photonic crystal fiber for lower indexed chemical sensing 
    Asaduzzaman, Sayed; Ahmed, Kawsar; Arif, Md. Faizul Huq; Morshed, Monir (IEEE Xplore, 2016-06-09)
    In this paper, a simple two layer photonic crystal fiber has been proposed. The proposed PCF shows higher sensitivity as a chemical sensor for lower refractive index chemicals Ethanol and Methanol. The proposed structure ...
  • 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 ...
