摘要: An optical fiber adapted to carry optical power for powering an electrical device and also optionally adapted to carry optical data for signal processing. The optical fiber capable of carrying both optical data and optical power includes a central data waveguide region that carries data light and an annular power waveguide region concentrically surrounding the data waveguide region and adapted to carry relatively large amounts of optical power. A first annular isolation region between the data and power waveguide regions and that includes microstructures serves to optically isolate the waveguide regions. An outer annular isolation region serves to confine power light to the power waveguide region and contributes to the bend-resistance of the optical fiber. An optical power and optical data distribution system that utilizes the optical fiber is also described.

摘要: Shunt fibers having a photonic bandgap cladding region including one or more hollow guiding regions of which one guiding region is configured as the core and one or more other guiding regions are configured as shunts, respectively, provide nearly single mode transmission in the core. The effective mode index of unwanted core modes and modes in one or more shunts are matched closely enough such that higher order modes will selectively couple to the shunt modes by resonant phase matching in the presence of fiber variations. The shunts are designed to have relatively higher losses thereby effectively dissipating power in the higher order modes at a faster rate.

摘要: An optical apparatus includes an optical fiber (13). A plurality of individual optical fiber deformation structures, comprising e.g. acoustic wave propagation members (18) and acoustic wave generators (24), are positioned adjacent along a length of the optical fiber. Each of an individual optical fiber deformation structure introduces a mechanical or index deformation of a portion of the optical fiber (36) (e.g. by a flexural acoustic wave) to create perturbations in the optical modes in the fiber and provide a coherent coupling between two modes in the optical fiber. This apparatus provides a wavelength tunable bandpass filter (e.g. acousto-optic tunable filter, AOTF) and can be used to recover the gain flatness of erbiumdoped fiber amplifiers (EDFA) or as add/drop filter.

摘要: An optical filter comprises a multi-mode waveguide (W2) and a single-mode waveguide (W1, W3) coupled in series, the interference of different modes at the multiple-mode/single-mode interface being effective to filter an optical signal propagating through the waveguides to provide a desired wavelength response characteristic. The offset between the waveguides may be varied to control the filter characteristic. The filter may be formed in the cavity of a laser to produce an output having a comb-filter characteristic. It may be used as channel selector in WDM systems.
