Fiber Bragg gratings in pure-silica polarization maintaining photonic crystal fiber were photowritten and characterized for their responses to temperature, axial strain and hydrostatic pressure.
We report on fiber Bragg gratings in all-solid photonic bandgap fiber that composed of a triangular array of high-index Ge-doped rods in pure silica background with fluorine-doped index-depressed layer surrounding the Ge-doped rod. Fiber Bragg gratings were photowritten with 193 nm ArF excimer laser and characterized for their response to strain, temperature, bending and torsion. These gratings couple...
Epitaxial growth of 4H-SiC is reported in a horizontal low-pressure hot-wall (LP-HW-CVD) reactor at temperature 1580degC and 100 mbar. The substrates were Si-face, n-type, 4H-SiC oriented 8deg off-axis toward the [1 12 macr 0] direction. Surface of SiC epitaxial layers were studied. Atomic force microscope (AFM) and scanning electron microscopy (SEM) were used to investigate the epitaxial layer surface...
Fiber Bragg gratings in pure-silica polarization-maintaining photonic crystal fiber were photowritten by use of two-photon ultraviolet excitation and characterized for their responses to temperature, axial strain, and hydrostatic pressure. The two resonance wavelengths corresponding to the two polarization axes show the same response to temperature and axial strain but different response to hydrostatic...
