Induced Bragg Gratings in Optical Fibers and Waveguides Using an Ultrafast Infrared Laser and a Phase Mask

Figure 6

Comparison of modeled (black) and experimental (gray) spectra for an irradiation intensity below the type I-IR to type II-IR transition (  W/cm2). Inset is the profile used to model the spectrum; fringe spacing is not to scale in figure.
