Welcome to Fiber Lasers and Sensors Group

Our research group lead by Prof. Balaji Srinivasan is dedicated to exploring and developing novel optical fiber-based solutions for real-world problems in industrial, defense, and healthcare applications. The thrust areas of our research may be broadly classified as: ​

  • High power fiber lasers & amplifiers 

  • Distributed fiber sensors

  • Fiber Bragg grating sensors

Currently, we are exploring a variety of novel optical fiber-based devices and subsystems for several of the above applications. Specific areas of research include:

  • Narrow linewidth fiber lasers and amplifiers

  • Power scaling of fiber lasers and amplifier through coherent beam combination

  • Generation and decomposition of optical beams with orbital angular momentum (OAM)

  • Distributed acoustic sensing using coherent Rayleigh backscattering

  • Distributed strain/temperature sensing based on Raman/Brillouin scattering

  • Acoustic emission sensing based on fiber Bragg grating sensors and interrogators

  • Underwater optical communication
