TL;DR: In this article, it was shown that the sound mode in displacive-type ferro-electrics changes into a new collective mode near the Curie point through strong coupling with the soft mode.

TL;DR: In this paper, composite optical waveguide structures or mode transformers (1300) and their methods of fabrication and integration are disclosed, wherein the structures or modes transformers are capable of bi-directional light beam transformation between a small mode size waveguide and a large mode size Waveguide.
Abstract: Composite optical waveguide structures or mode transformers(1300) and their methods of fabrication and integration are disclosed, wherein the structures or mode transformers are capable of bi-directional light beam transformation between a small mode size waveguide and a large mode size waveguide. One aspect of the present invention is directed to an optical mode transformer (1300) comprising a waveguide core (1345) having a high refractive index contrast between the waveguide core (1345) and the cladding (1350 or 1310), the optical mode transformer (1300) being configured such that the waveguide core (1345) has a taper wherein a thickness of the waveguide core tapers down (1348) to a critical thickness value, the critical thickness value being defined as a thickness value below which a significant portion of the energy of a light beam (1341) penetrates into the cladding layers (1350 or 1310) surrounding the taper structure thereby enlar in the small mode size.

TL;DR: In this article, the authors show that the behavior of the multimode oscillating is only dependent on the ratio of mode frequency and relativistic cyclotron frequency and is in agreement with that described by single mode theory.
Abstract: Mode competition — interaction between a mode and another mode — is due to the non-linearity of the relativisitc factor γ. At the beginning of a multimode oscillating, the behavior of the multimode oscillating is only dependent on the ratio of mode frequency and relativistic cyclotron frequency and is in agreement with that described by single mode theory. In non-linear domain mode interaction depends on both amplitudes of A1 and A2 and phase difference Δi of the two modes. The main effect of mode interaction is that excitation of the parasitic mode suppresses growth of the operating mode.

TL;DR: In this paper, higher-order-mode fibers with very large mode area are shown to be naturally resistant to bend induced mode distortion, an important limitation on amplifier fibers, and simulations and measurements display resistance of these fibers to bending.

16 Dec 2004TL;DR: In this article, the authors proposed a mode converter for optical communication, which consists of a first waveguide, a second waveguide and omnidirectional reflectors that are disposed on either side of the first-waveguide and have forward reflectivity with respect to a mode propagating in the waveguide.
Abstract: Provided is a mode converter for use in optical communication. The mode converter includes a first waveguide, a second waveguide optically coupled into the first waveguide, and omnidirectional reflectors that are disposed on either side of the first waveguide and have forward reflectivity with respect to a mode propagating in the first waveguide. The mode converter provides minimum loss coupling between either optical fiber or low index difference waveguide and a high index contrast waveguide. Furthermore, the mode converter achieves high, bi-directional optical coupling over a wide wavelength range with a simple manufacturing process.
