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 line-width 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 back-scattering

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

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

  • Underwater optical communication
