Research Interests

  • Near and Mid-Infrared Photonics Group: This group is led by Prof. Gayathri Bharathan and aims to make significant progress in developing near and mid-infrared (mid-IR) fiber lasers, fiber amplifiers, and fiberized integrated components. The future of near and mid-IR fiber lasers and fiberized integrated components is promising, as they provide several benefits over conventional lasers. These lasers have the potential to revolutionize various applications such as spectroscopy, sensing, and medical diagnostics due to their ability to generate high-power beams in a wide range of wavelengths from 1 to 12 μm. The development of mid-IR fiber lasers is now an active topic of research. Nevertheless, the development of mid-IR fiber lasers is still in its infancy due to the unavailability of fiber-coupled components compared to the near-infrared (near-IR) region. As a result, fiberized integrated components such as waveguides, couplers, WDM, and so on are becoming increasingly important in developing all-fiber mid-IR lasers because they facilitate the transfer from the laboratory to practical applications. This group will concentrate on designing and developing mid-IR compatible integrated components and, hence, developing all-fiber mid-IR laser cavities. Furthermore, this group aims to produce novel and innovative results, such as supercontinuum broadband sources in the molecular fingerprint region (2 - 12 µm), employing near and mid-IR ultrashort pulsed lasers as pump sources. These broadband sources could potentially be employed in various applications, including environmental and health monitoring.
