| Abstract | Hollow-core photonic bandgap fibers (HC-PBFs) have been recently demonstrated as a powerful technology in the field of gas sensing. The long interaction path lengths achievable with these fibers are advantageous for the detection of weakly absorbing gases such as methane. However, using long path lengths yield to very high insertion times of the gas into the fiber. In this paper, an alternative configuration based on a multi-coupling gap HC-PBF system to detect methane is proposed to overcome this problem. For this purpose, a conventional configuration using one long piece of HC-PBF is compared to this novel configuration, which uses four shorter pieces of HC-PBF with the same overall length as the first configuration. The experimental results are validated theoretically modeling the normalized pressure inside the fiber. A very good correlation between the experimental data and the theoretical fit is obtained, demonstrating the feasibility of the system proposed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
