| Abstract | The near-infrared supercontinuum light was generated in a single mode optical fiber by the femtosecond pulses from an unamplified Ti:sapphire laser. The light source possesses properties of high repetition rate, peak power, and low optical damage, and thus can used for optical sensors. Supercontinuum generation is a complex nonlinear phenomenon that is characterized by the dramatic spectral broadening of intense light pulses passing through a nonlinear material. Special fibers, such as the fluoride fiber and tapered fiber, spanning over three octaves from UV to 3.85 m and over two octaves from 370~1550 nm, respectively, are used to generate the supercontinuum. The spectra span more than an octave and retain the longitudinal mode structure of the mode-locked laser source, which recently led to spectacular advances in optical frequency metrology. In this study, a conventional single mode optical fiber with a cladding-free central section immobilized metal nanoparticles was used to generate the near-infrared supercontinuum light. The absorption spectrum of nanoparticals on the optical fiber can be measured by the homemade tunable near-infrared supercontinuum light source from the single mode fiber. It offers a simple and cost-effective method to generate a near-infrared light source to serve for spectral measurements and achieving the fiber-optic sensing. |

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.
