Nowadays, fiber Bragg gratings (FBGs) indisputably represent one of the most powerful in-fiber tools for the development of effective sensing and communication devices.Within this fiber technology, th...
Intensity-modulated fiber Bragg grating (FBG) sensors, compared with normal wavelength-encoding FBG sensors, can reduce the cost of sensor system significantly by using cost-efficient optical power...
A novel two-dimensional (2-D) tilt sensor is demonstrated by incorporating only twofiber Bragg gratings (FBGs) with a hybrid pendulum transducer. The pendulum transducer is specially designed with hol...
A novel two-dimensional (2-D) clinometer has been demonstrated by attaching two fiber Bragg gratings (FBGs) on a deliberately designed pendulum composed of a tapered cylin-drical beam and a mass. Due ...
Mean index changes >10 -3 were obtained in non-hydrogen-loaded ~3% GeO 2 -doped silica fibers with a 9/40 μm core/cladding diameter using a cw 244-nm-Ar + -laser. Core stress changes are positive indi...
A two-dimensional (2D) tilt sensor based on three optical fiber Bragg gratings (FBGs) isproposed and demonstrated. Experimental results show that a high measurement sensitivity of 192 pm/◦ and r...
A novel free-spectral range (FSR) tunable Fabry–Perot filter (FPF) with two superimposed fiber Bragg gratings (SFBGs) is proposed and experimentally demonstrated. The SFBGs, initially uniform in perio...
We have written for the first time high quality Bragg grating structures in highly nonlinear single mode bismuth oxide fibers . The grating inscription method is presented along with the annealing beh...
A novel concept enabling ultra low-loss tunable ROADM is proposed and demonstrated. Wavelength selection is achieved using tilted fiber Bragg gratings in a MEMS controlled mirror cavity.
