“…The first process has been theoretically analyzed in detail in several papers utilizing Green Function method (also called Volume Current method) by adopting a cladding with infinite thickness [17,18]. Although using this method, various aspects of the radiation can be calculated, such as the spread of beam, spectrum and the strength, it is much more straightforward to examine the coupled mode propagation employing its derivation -the phase match condition [19].…”

Abstract:We describe a detailed investigation on tilted fiber Bragg grating (TFBG) structures with tilted angles exceeding 45°. In contrast to the backward mode coupling mechanism of Bragg gratings with normal and small-tilting structures, the ex-45°TFBGs facilitate the light coupling to the forward propagating cladding modes. We have theoretically and experimentally examined the mode coupling transition of TFBGs with small, medium and large tilt angles. In particular, we have conducted experiments to investigate the spectra and far field distribution, and temperature, strain and refractive index sensitivities of ex-45° devices. It has been revealed that these ex-45°gratings exhibit ultra-low thermal sensitivity. As in-fiber devices, they may be superior to conventional Bragg and long period gratings when the low thermal cross sensitivity is required.

“…In this work, we applied a theoretical model proposed by Holmes et al [2] to simulate the properties of the slanted FBGs written in the special designed fiber. Our simulation program has been extended to take into account the effect of the core-cladding boundary by using the correction relation between the Green functions in the free space and in the cylindrical waveguide.…”

Abstract-A wavelength monitor based on a pair of tilted fiber Bragg gratings is reported. The monitor exhibits a subpicometer wavelength selectivity over a broad wavelength range (>30 nm), and a low insertion loss (<1 dB) for laser light with polarization matching the reference polarization of the device. Simulations show that a wavelength coverage up to 100 nm is possible and that the resolution degradation due to changes in the polarization state can be avoided by proper design of the gratings.
