摘要： In some examples, an optical fiber may include a clad portion and an exposed fiber core that extends from the clad portion. Multiple such optical fibers may be included in a fiber bundle having a condensed region of fiber cores spaced at a first center-to-center spacing and a non-condensed region of clad portions spaced at a second center-to-center spacing greater than the first center-to-center spacing. Such optical fibers may be formed with exposed fiber cores ab initio.

摘要： An optical fibre designed to simultaneously attenuate the effect of modulation instability and stimulated Raman scattering. A first solution proposes to use non-zero dispersion shifted fibres in the normal dispersion regime to reduce both influences at the same time. A further solution proposes to implement corresponding filter elements in the signal line. A still further solution proposes to additionally provide absorber elements for the Raman wavelengths or to design the core as a leaky one for these wavelengths.

摘要： An optical sensor formed from an optical waveguide having at least one core surrounded by a cladding and a large diameter generally D-shaped portion is disclosed. Axial or compressive strain across the D-shaped cross section may be determined by measuring the change in polarization or birefringence of the light output from the sensor. A layer responsive to a parameter may be disposed on a flat portion of the D-shaped portion of the sensor. The refractive index of the layer changes and/or the layer applies a strain on the sensor in response to the parameter. Changes in the refractive index of the layer alters the light output from the sensor, which is measured over time and correlated to the parameter.

摘要： Provided herein are photonic devices configured to display photonic band gap structure with a degenerate band edge. Electromagnetic radiation incident upon these photonic devices can be converted into a frozen mode characterized by a significantly increased amplitude, as compared to that of the incident wave. The device can also be configured as a resonance cavity with a giant transmission band edge resonance. In an exemplary embodiment, the photonic device is a periodic layered structure with each unit cell comprising at least two anisotropic layers with misaligned anisotropy. The degenerate band edge at given frequency can be achieved by proper choice of the layers' thicknesses and the misalignment angle. In another embodiment, the photonic device is configured as a waveguide periodically modulated along its axis.
