چکیده

The influence of the fiber geometry on the point-by-point inscription of fiber Bragg gratings using a femtosecond laser is highlighted. Fiber Bragg gratings with high spectral quality and strong first-order Bragg resonances within the C-band are achieved by optimizing the inscription process. Large birefringence (1.2x10(-4)) and high degree of polarization-dependent index modulation are observed in these gratings. Potential applications of these gratings in resonators are further illustrated.

Point-by-Point Femtosecond Laser Inscription of Bragg Gratings In High NA (>0.4) Germania-Doped Optical Fibre

Using point-by-point femtosecond laser inscription, a fibre Bragg grating (FBG) was written in a high NA germania-doped fibre. Thermal tests demonstrated that the FBG could withstand temperatures up to 800°C without significant effects on reflectivity.

Optimization of Bistability in Nonlinear Chalcogenide Fiber Bragg Grating for All Optical Switch and Memory Applications

We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...

Thermal properties of fiber Bragg gratings inscribed point-by-point by an infrared femtosecond laser

Direct, point-by-point inscription of fiber Bragg gratings by infrared femtosecond laser had been recently reported. Response of these gratings to annealing at temperatures in range 500C to 1050C is studied for the first time. Gratings inscribed by infrared femtosecond lasers were thermally stable at temperatures up to 900C, representing a significant improvement in comparison with the “common”...

Femtosecond-laser-inscribed sampled fiber Bragg grating with ultrahigh thermal stability.

We have successfully fabricated a series of sampled fiber Bragg gratings with easily adjustable sampling periods and duty cycles using an 800 nm femtosecond laser point-by-point inscription. The thermal stability of the fabricated fiber gratings was investigated using isochronal annealing tests, which indicated that the fiber gratings are capable of maintaining high reflectivity at temperatures...

Femtosecond laser inscription of Bragg grating waveguides in bulk diamond.

Femtosecond laser writing is applied to form Bragg grating waveguides in the diamond bulk. Type II waveguides are integrated with a single pulse point-by-point periodic laser modification positioned toward the edge of the waveguide core. These photonic devices, operating in the telecommunications band, allow for simultaneous optical waveguiding and narrowband reflection from a fourth-order grat...
