Optical image of a perpendicularly cleaved fiber with 3% reflectivity. The top edge of the image shows the fractured region (caused by cleaver) in the cladding (diameter ).
Optical image of a MOD coated fiber end. (a) Uniform coating resulting in (b) Nonuniform coating resulting .
SEM micrograph of (a) uniformly coated fiber end with (b) A magnified image from the center of the fiber end in (a) shows the grains. Note that the dark patch in the center of a and b is due to the damage from repeated scanning at higher magnification.
Raman spectrum of uncoated (black/bottom) and coated fibers (red/middle and blue/top). Red: nonuniformly coated fiber showing anatase phase; Blue: uniformly coated fiber showing rutile phase. The spectra are shifted along the -axis for clarity.
Interferometric testing system. (a) Schematic and (b) actual.
List of liquids in which the fiber was immersed for 24 h to test for its robustness. The shown reflectivities did not change during the immersion time.
