- Development of Photonic Crystal Fiber based Physical Sensors
Photonic crystal fibers (PCFs) are a kind of optical fibers that use photonic crystals to form the cladding around the core. Photonic crystals are low-loss periodic dielectric medium constructed using a periodic array of microscopic air holes that run along the entire fiber length. PCF-based sensors are advantageous over standard optical fiber sensors in many aspects. They not only have great design flexibility but also their holey internal structure can be filled with analyte so that a controlled interaction can take place between propagating light and the analyte sample. This greatly enhances the sensitivity of fiber optic sensors as well as opens up a new direction for making advanced portable sensors. PCF sensors have a wide range of applications. Measurement of different physical parameters like temperature, pressure, strain, twist, torsion, curvature, bend, electromagnetic field and refractive index are a few of them. The research and entrepreneurial communities are interested in this topic due to multiple applications of these sensors in various fields, including civil engineering and the aeronautical and automotive industries. The objective of this project is to develop PCFs for sensing any of the aforementioned physical parameters in the optical and terahertz regimes. This shall be achieved through design, simulation, fabrication and characterisation.
- Applications of Nanophotonics in Optical Fiber Technology
Nanophotonics is an exciting new field of nano-science that deals with the interaction of light with matter on a nanometer size scale. It is a field in which photonics merges with nanoscience and nanotechnology, providing challenges for fundamental research and creating opportunities for new technologies and applications. Nanotechnologies can be exploited by incorporating nano-features into optical fibers to achieve manipulation of light in ways not possible with conventional optical fiber waveguiding techniques. This additional functionality offers great potential of fiber-based nanotechnology for applications in communications, optical computation and medical technology for optical waveguides.
