主　　题：ultrafast laser optical fiber fiber Bragg grating 

摘      要：Different types of microstructures including microchannels and microslots were made in optical fibers using femtosecond laser inscription and chemical *** with UV-inscribed fiber Bragg gratings,these microstructures have miniature,robustness and high sensitivity features and have been used to implement novel devices for various sensing *** fiber microchannels were used to detect the refractive index change of liquid presenting sensitivities up to 7.4 nm/refractive index unit(RIU)and 166.7 dB/RIU based on wavelength and power detection,respectively.A microslot-in-fiber based liquid core waveguide as a refractometer has been proposed and the device was used to measure refractive index,and a sensitivity up to 945 nm/RIU(10−6/pm)was *** filling epoxy in the microslot and subsequent UV light curing,a hybrid waveguide grating structure with polymer core and glass cladding was *** obtained device was highly thermal responsive,demonstrating a linear coefficient of 211 pm/◦C.
