We have studied the performance of silica single mode hollow-core optical fibers in optical communication. Silica single mode optical fibers form the core of high capacity telecommunication network. Hollow-core optical fibers have an air filled core surrounded with micro structured glass cladding allowing high level of light confinement. Light guiding mechanism of Bragg, photonic band gap and antiresonant fibers were considered. Nested antiresonant nodeless fibers and conjoined fibers are the two most promising antiresonant fiber designs for achieving ultra-low attenuation. Mode field adaptation using graded index multimode fiber; we have achieved record low insertions loss and also suppressed higher order modes. Deposition of anti-reflective coating allowed reducing unwanted back reflections. We have developed an approach for a hollow-core optical fiber of single mode interconnection based on a modified fiber array technology which solved the problem of back reflections by applying optical coating. Fundamental mode coupling was achieved by using mode theory adapters in the form of graded index multimode fibers. How to cite this article: Yadav UK. (2022).
