Kawsar Ahmed,Sawrab Chowdhury,Bikash Kumar Paul,Md. Shadidul Islam,Shuvo Sen,Md. Ibadul Islam,Sayed Asaduzzaman +6 more
TL;DR: The proposed single-mode porous core hexagonal PCF is expected to be useful for convenient broadband transmission and numerous applications in the areas of THz technology.
Journal ArticleDOI
Liquid-infiltrated photonic crystal fiber for sensing purpose: Design and analysis
Md. Shadidul Islam,Bikash Kumar Paul,Kawsar Ahmed,Sayed Asaduzzaman,Sayed Asaduzzaman,Md. Ibadul Islam,Sawrab Chowdhury,Shuvo Sen,Ali Newaz Bahar +8 more
TL;DR: In this paper, a photonic crystal fiber based on a modified hexagonal structure has been discussed and demonstrated modal analysis precisely, which shows higher sensitivity as a chemical sensor for lower refractive index chemicals such as Water, Ethanol and Benzene.
Journal ArticleDOI
Design of single mode spiral photonic crystal fiber for gas sensing applications
Md. Ibadul Islam,Kawsar Ahmed,Sayed Asaduzzaman,Sayed Asaduzzaman,Bikash Kumar Paul,Touhid Bhuiyan,Shuvo Sen,Md. Shadidul Islam,Sawrab Chowdhury +8 more
TL;DR: In this paper, a spiral shape photonic crystal fiber (S-PCF) has been suggested as a gas sensor for detecting toxic or colorless gases as well as monitoring the air pollution by metering gas condensate elements in production facilities.
Journal ArticleDOI
Design of a porous cored hexagonal photonic crystal fiber based optical sensor with high relative sensitivity for lower operating wavelength
TL;DR: In this article, the authors proposed a porous cored hexagonal (P-HPCF) where cladding contains five layers with circular air holes and core vicinity is formed by two layered elliptical air holes.
Journal ArticleDOI
Design of highly sensible porous shaped photonic crystal fiber with strong confinement field for optical sensing
TL;DR: In this paper, a porous shaped photonic crystal fiber (P-PCF) has been proposed for chemical sensing purposes where both core and cladding air holes are rearranged in porous manner.
