摘要： A resistive heating element is used to fabricate a long-period grating mode converter. The resistive heating element creates a localized heating zone for creating an asymmetric perturbation at a periodic series of axial locations along the length of a segment of optical fiber that supports the propagation of both a symmetric mode and an asymmetric mode. In a further technique, a grating is written with an index contrast value that is higher than a selected optimum value. The heating element is then used to anneal the fiber segment so as to reduce the contrast value of the grating to the selected optimum value.

摘要： An in-line polarization extinction ratio (PER) monitor that generates a value of an optical signal's PER from a single measurement, without requiring the optical transmission signal path of the system to be directly coupled into a separate measurement device. The polarization extinction ratio may be defined as: 1010g(P Ex /P Ey ), where P Ex is the power of the optical signal propagating along the "x axis" and P Ey is the power propagating along the orthogonal "y axis" (with the z-axis defined as a longitudinal optical axis of the system and the x-y plane orthogonal to this direction of propagation). The PER monitor comprises a section of optical fiber (preferably birefringent or with induced birefringency), with a pair of gratings formed along the fiber and oriented to out-couple orthogonal components of the propagating signal. Photodetectors are used to convert the scattered light into electrical signal equivalents and then processed to yield the PER value.

摘要： A method and system for measuring chromatic dispersion, experienced by ASK/PSK modulated optical signals, are provided. Dispersion measurement is enabled either by encoding an additional overhead at lower baud rate or by monitoring signal SOP or RF spectrum of signal SOP. The bulk chromatic dispersion of the link is measured by analyzing the dispersion broadening of the overhead constellation or signal temporal diagram, or time-overlapped signal diagram, or overhead spectrum. This information is used to reduce the computation time required for electronic recovery of a highly dispersed signal.

摘要： A Raman distributed feedback (DFB) fiber laser is disclosed. It includes a pump source and a Raman gain fiber of a length smaller than 20 cm containing a distributed feedback (DFB) grating with a discrete phase structure located within no more than 10 % off the center of the grating and wherein the Raman DFB fiber laser generates a laser signal with an optical spectrum, which has an optical bandwidth at half maximum optical intensity of less than 1 gigahertz (GHz) (wherein a maximum intensity frequency is different from the frequency of the pump laser). The Raman laser includes compensation for the nonlinear phase change due to Kerr effect and thermal effect resulting from absorption of the optical field, thus enhancing the conversion efficiency.

摘要： A conically tapered optical fiber with a small half-angle γ (e.g., less than 10 -2 ) has been found able to support whispering gallery mode ( WGM) resonances and can therefore be used to form a high-Q cavity. This finding has led to the ability to measure angstrom-level variations in the radius of an optical fiber by viewing the resonance spectrum at various locations where a sensor contacts an optical fiber being measured. An evaluation process is proposed where a microfiber sensor is brought into contact with a target fiber and the created WGM resonance is measured so that location radius variation can be characterized. The sensor is then removed from the target fiber and re-positioned to contact the fiber to another location to repeat the evaluation.

摘要： A dispersion-compensating system and a dispersion-compensating fiber have an improved figure of merit and effective area. The dispersion-compensating system comprises a bulk dispersion-compensating module for providing optical-domain bulk dispersion compensation for an optical signal transmission. Additionally, the system may further comprise residual dispersion compensation, which can be performed in the electrical domain following coherent detection of both amplitude and phase of an optical signal. The dispersion-compensating fiber comprises an up-doped core region; a down-doped trench; an up-doped ring; and an outer cladding, and is configured to have a high figure of merit (FOM).

摘要： Among other things, a communication line is attached along a target surface of a building by laying out the line from a tool. An outer surface of the line is in a temporarily tacky condition as the line is laid out along the surface. The line is in the temporarily tacky condition based at least in part on an adhesive component having been pre-applied to the outer surface of the line. The line becomes non-tacky after it has been attached.

摘要： An optical fiber cable connector includes a ferrule subassembly, wherein a ferrule is mounted into a receptacle including a barrel section having a flange at its base. The ferrule subassembly is loaded into an enclosure having a plug housing at its lead end. The plug housing provides a connection between an endface of a multicore fiber mounted into the ferrule and a corresponding surface in a mating socket. A collar is rotatably mounted onto the barrel section such that it butts up against the flange. The barrel section fits within the collar and the collar fits within the plug housing. The ferrule, receptacle, barrel section, mounted multicore fiber, enclosure, and plug housing have a common longitudinal axis. The ferrule, receptacle, barrel section and mounted multicore fiber are thus continuously rotatable with respect to the enclosure and plug housing, thereby enabling rotational precise alignment of the multicore fiber within the enclosure.
