We report the first experimental observation of nonlinear propagation effects in fiber Bragg gratings, resulting in nonlinear optical pulse compression and soliton propagation. The solitons occur at frequencies near the photonic band gap of the grating; they are due to a combination of the negative dispersion of the grating, which dominates the ...

Birefringence Bragg Binary (3B) grating, quasi-Bragg grating and immersion gratings
SPIE Proceedings, 2014A volume phase holographic (VPH) grating achieves high angular dispersion and very high diffraction efficiency for the first diffraction order and for S or P polarization. However the VPH grating could not achieve high diffraction efficiency for non-polarized light at a large diffraction angle because properties of diffraction efficiencies for S and ...

Interrogation of fibre Bragg gratings with a tilted fibre Bragg grating
Measurement Science and Technology, 2004A new and efficient interrogation scheme suitable for monitoring the Bragg wavelengths of multiplexed fibre Bragg gratings is presented. The heart of the technique consists of a tilted and chirped fibre Bragg grating placed in front of a photodetector linear array.

Fabrication of Bragg Grating Structures in Silicon
Physica Scripta, 2002A fabrication process to realise very short period grating structures in silicon has been developed. The period of a first order Bragg grating operating at a wavelength of 1.55 μm is 230 nm. The grating structures have been directly written to PMMA resist using an electron beam pattern generator.

Bragg diffraction of a read beam is studied theoretically when the refractive-index grating is placed inside a Fabry–Perot cavity. Diffraction efficiency, angular selectivity, and signal-to-noise ratio are largely enhanced compared with those for the bare Bragg grating, which may permit the use of low-efficiency or short-length materials as well.
