Diffraction properties of highly birefringent liquid-crystal composite gratings.
We have fabricated electrically switchable holographic gratings, using Polaroid Corporation's DMP-128 photopolymer filled with the nematic liquid crystal E7. It is shown that a coupled-wave theory that includes the effects of the birefringence of the liquid crystal must be used to explain the diffraction properties of these anisotropic volume gratings. Furthermore, a detailed comparison of theo...
متن کاملPolarization effects in birefringent Bragg gratings with a Kerr nonlinearity
We show that a Kerr-nonlinear birefringent Bragg grating allows the investigation of three regimes of nonlinear pulse propagation. The regimes are entered by tuning the frequency of the pulse relative to the stop band of the grating. Tuning away from the stop band lowers the intensity necessary for soliton formation but increases the intensity necessary to observe polarization instability. We d...
متن کاملNonlinear pulse propagation in birefringent fiber Bragg gratings.
We present two sets of equations to describe nonlinear pulse propagation in a birefringent fiber Bragg grating. The first set uses a coupled-mode formalism to describe light in or near the photonic band gap of the grating. The second set is a pair of coupled nonlinear Schroedinger equations. We use these equations to examine viable switching experiments in the presence of birefringence. We show...
متن کاملPolarizing beam splitters constructed of form-birefringent multilayer gratings
We introduce a novel polarizing beam splitter that uses the anisotropic spectral reflectivity (ASR) characteristics of a high spatial frequency multilayer binary grating. By combining the form birefringence effect of a high spatial frequency grating with the resonant reflectivity of a periodic multilayer structure, the ASR characteristics for the two orthogonal linear polarizations are obtained...
متن کاملPolarizing beam splitter based on the anisotropic spectral reflectivity characteristic of form-birefringent multilayer gratings.
We introduce a novel polarizing beam splitter that uses the anisotropic spectral reflectivity (ASR) characteristic of a high-spatial-frequency multilayer binary grating. Such ASR effects allow us to design an optical element that is transparent for TM polarization and reflective for TE polarization. For normally incident light our element acts as a polarization-selective mirror. The properties ...
