FUTURE PROJECTS

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, gas 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.

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.

White light generation using photonic crystal fiber

Rapid developments in Photonic Crystal Fibers (PCFs) driven by novel engineering techniques continue to push the limits of optical fiber technology and its applications. This major advancement in PCFs is essentially due to its high design flexibility and geometrical economy. PCFs are the very useful for white light generation. A white light source is usually understood to be a light source generating white light in the visible range of the electromagnetic spectrum. i.e., with a white perception for the human eye. Some typical types of white light sources are incandescent lamps, gas discharge lamps, fluorescent lamps, Light Emitting Diode (LED), and laser based RGB sources. Important properties of white light sources include the colour temperature, colour rendering index, luminous efficacy, temporal coherence, spatial coherence, operation lifetime, radiant flux, and its ability to operate continuously. Many white light sources are required for various lighting applications (indoor and outdoor), where one often needs to generate a substantial luminous flux over extended times. The energy efficiency, largely determined by the luminous efficacy, is then particularly important. Moreover, the attractive properties of PCFs include high nonlinearity, high birefringence, endlessly single mode, and large mode area, etc. These properties make PCFs natural candidates for supercontinuum generation. Efficient supercontinuum generation relies on an endlessly single mode nonlinear medium with tailored dispersion and nonlinearity – essentially a highly nonlinear PCFs. The applications of white light source in illumination such as signs, traffic signals, decorative and architectural lighting, and automobile daylight running lights and brake lights. Other applications of white light source include photography, spectroscopy, and colorimetry. The advantages of white light sources are many, such as their low maintenance cost, tuneability, compact size and robustness, but they also have environmentally important features such as longevity, high energy efficiency and not containing any environmentally harmful substances. The successful application of white light sources will be provided significant economic and environmental benefits.
