On the edge of the bandgap in a fiber Bragg grating(FBG) narrow peaks of high transmission exist at frequencies where light interferes constructively in the forward direction.
Bragg-Angle Diffraction in Slant Gratings Fabricated by Single-Beam Interference Lithography
Slant Grating Single-Beam Interference Lithography Bragg-Angle Diffraction
2013/1/30
A single-beam interference-lithography scheme is demonstrated for the fabrication of large-area slant gratings, which requires exposure of the photoresist thin film spin-coated on a glass plate with p...
Strong fiber Bragg gratings in Bi-Al co-doped H 2 -loaded optical fibers using CW-Ar + laser
Fiber Bragg gratings photosensitivity Lasers fiber
2015/5/22
Bragg gratings with reflectivity >93% were fabricated in Bi-Al co-doped H 2 -loaded optical fibers. Average index changes as high as +2.5×10 -3 were obtained. Positive core stress changes indicate a c...
