Multichannel optical coupler array

TL;DR: In this article, the polarization axes of vanishing core waveguides are oriented or aligned without the need to adjust the orientation of each individual VC waveguide, which is called PM-PROFA coupler.

TL;DR: The configurable optical fiber polarization mode coupler as discussed by the authors is capable of providing a low-loss, high-coupling coefficient interface with high accuracy and easy alignment between a plurality of optical fibers (or other optical devices) with a first channel-to-channel spacing, and an optical device having a manifold of closely-spaced waveguide interfaces with a second channel-To-Channel spacing, where each end of the optical fiber coupler array is configurable to have different channel to channel spacing.

TL;DR: In this paper, the optical coupler array can provide a low-loss, high-coupling coefficient interface with high accuracy and easy alignment between a plurality of optical fibers (or other optical devices) with a first channel-to-channel spacing, and an optical device having a plurality-of- closely-spaced waveguide interfaces with a second-channel-tochannel spacing.

TL;DR: An optical coupler array can include an elongated optical element having a coupler housing structure and at least one longitudinal waveguide embedded in said housing structure as mentioned in this paper, which can have an outer cross sectional shape comprising a first side comprising one or more curved portions and a second side comprising flat portions.

TL;DR: In this article, an improved fiber optic probe assembly for low light spectrographic analysis improves response to subtle light-matter interactions of high analytical importance and reduces sensitivity to otherwise dominant effects.

TL;DR: In this paper, an optical transmission fiber is formed to include a relatively low-index, relatively thin outer cladding layer disposed underneath the protective polymer outer coating, which allows for the stray light to leak into the outer coating in a controlled, gradual manner so as to minimize heating of the coating associated with the presence of stray light.

TL;DR: In this article, a novel polarization maintaining optical fiber, which can be used as a high-power polarization maintaining fiber laser or amplifier, is described, which is used in any application where polarization stability is important, and will be useful in telecommunications applications in particular for reducing polarization mode dispersion.

TL;DR: In this article, an optical fiber arrangement has at least two optical fibre sections, each optical fibre section defining an outside longitudinally extending surface, and the outside longitudinal extending surfaces are in optical contact with each other.
