| Abstract | This study proposes a dielectric terahertz (THz) porous core fibre with ultra-high birefringence and near zero dispersion-flattened properties. The finite element method is used to design and analyse properties of the proposed THz fibre. The proposed porous core crystal fibre has a triangular lattice with microstructured circular air holes in the outer cladding and elliptical air holes in the core. The design exhibits a high birefringence of 7 × 10−2 and a low effective material loss of 0.1 cm−1 at the operating frequency of f = 1 THz. It also shows nearly zero flattened dispersion with an absolute dispersion variation of ±0.05 ps/THz/cm in the frequency range of 1.3 to 2.2 THz. Power fraction and confinement loss are also reported in this study. The proposed THz porous fibre is deemed suitable for polarisation-maintaining THz wave guidance. |

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.
