Highly polarized all-fiber thulium laser with femtosecond-laser-written fiber Bragg gratings.
We demonstrate and characterize a highly linearly polarized (18.8 dB) narrow spectral emission (<80 pm) from an all-fiber Tm laser utilizing femtosecond-laser-written fiber Bragg gratings. Thermally-dependent anisotropic birefringence is observed in the FBG transmission, the effects of which enable both the generation and elimination of highly linearly polarized output. To our knowledge, this i...
متن کاملOptical loss mechanisms in femtosecond laser-written point-by-point fibre Bragg gratings.
Fibre Bragg gratings inscribed with the point-by-point method using a Ti-sapphire femtosecond laser operating at 800 nm are shown to display strong increasing attenuation towards shorter wavelengths with a large and spectrally sharp recovery observed below 400 nm. The origin of this loss is shown to be Mie scattering, and the sharp recovery in the transmission results from wavelength dependent ...
متن کاملIntrinsic apodization of Bragg gratings written using UV-pulse interferometry
We present a new interferometric technique to write apodized Bragg gratings. Along the fiber, two UV-pulses interfere with a variable time delay creating a gaussian apodization profile which strongly reduces the reflectivity side-lobes. This method allows writing of truly apodized gratings by single exposure of a uniform phase-mask. Introduction: In optical communication systems, applications o...
متن کاملDirect laser written waveguide-Bragg gratings in bulk fused silica.
Optical waveguides that incorporate Bragg gratings have been written in bulk fused silica by using the femtosecond laser direct-write method and without the need for lithography or ion-beam techniques. A single manufacturing process is used to create waveguide-Bragg grating reflectors for operation in the C band.
متن کاملExtreme Environment Sensing Using Femtosecond Laser-Inscribed Fiber Bragg Gratings
The femtosecond laser-induced fiber Bragg grating is an effective sensor technology that can be deployed in harsh environments. Depending on the optical fiber chosen and the inscription parameters that are used, devices suitable for high temperature, pressure, ionizing radiation and strain sensor applications are possible. Such devices are appropriate for aerospace or energy production applicat...
