    Abstract: The present invention provides devices and methods for dispersion compensation. According to one embodiment of the invention, a dispersion compensating device includes a negative dispersion fiber having an input configured to receive the optical signal, the negative dispersion fiber having a length and dispersion sufficient to remove any positive chirp from each wavelength channel of the optical signal, thereby outputting a negatively chirped optical signal; an amplifying device configured to amplify the negatively chirped optical signal; and a nonlinear positive dispersion fiber configured to receive the negatively chirped optical signal. The devices of the present invention provide broadband compensation for a systems having a wide range of variable residual dispersions.

    Abstract: A wideband polarization splitter and combiner is fabricated using either fiber coupler technology or planar coupler technology. The device splits or combines wideband light signals without losing a substantial amount of spectral information. An antipodal phase generator is used to split a randomly polarized light signal into relatively wideband polarization components for use by polarization sensitive devices. The optical device is fabricated using polarization preserving fibers or waveguides, but it is intended for use in systems employing non-polarization-preserving fibers. The polarization splitter/combiner is also used as the basis for an isolator/circulator and a polarization controller. The polarization controller converts a randomly polarized light signal into a signal having a known and definite state of polarization.

    Abstract: An optical fiber preform is made by supplying the base glass reactant and the dopant glass reactant to a burner that generates a flame in which a stream of glass particles is produced. The burner moves with respect to a rotating mandrel to deposit layers of glass particles on the mandrel. During the deposition of a portion of the preform, the flow rate of the dopant glass reactant is varied in accordance with a first recipe of dopant flow as a function of burner position as the burner moves longitudinally along the substrate to form one of the layers. The flow rate of the dopant glass reactant varies in accordance with a second recipe of dopant flow as a function of burner position as the burner moves longitudinally along the substrate to form a layer adjacent to the one layer. The second recipe is different from the first recipe, and the flow rate of the dopant glass reactant changes during the step of moving the reaction zone to form the one layer.

    Abstract: An anti-abrasion and rockering system for an in-line skate. The skate includes a skate boot mounted on a chassis. The chassis includes two sidewalls which are parallel and opposite to each other. Each sidewall has a row of holes formed therein, such that the holes on the first sidewall align with and are opposite to the row of holes on the opposing sidewall. Two of the opposing sets of holes are oblong. A plurality of axles are disposed in the holes on the chassis so that the wheels are rotatably mounted on the axles and between the sidewalls of the chassis. The anti-abrasion and rockering system for the skate includes bushings disposed in the holes in the chassis. The bushings disposed in the oblong holes slide up and down in the holes. An anti-abrasion and rockering plate is disposed on the exterior of each sidewall. Each plate has a first and second row of holes for accommodating the axles. The first row of holes is misaligned so that some of the wheels on the skate are higher with respect to the skating surface than other wheel such that the front and rear wheels of the skate are rockered. The second row of holes is aligned so that all the wheels are at the same distance from the skating surface, so that the wheels are not rockered. To switch from the rockered to non-rockered state, the skater removes the plates from the chassis, turns the plates 180 degrees and reattaches each plate to the chassis.

    Abstract: An M.times.O multiplex/demultiplex device is disclosed. An M.times.N coupler is connected to an N.times.O coupler by phase shifting means. The phase shifting means provide N paths between the couplers, each path having an optical path length different from every other optical path length. The coupling region of the M.times.N coupler must provide for substantially uniform division of light power among the coupler branches when M are the launch ports. Similarly, the coupling region of the N.times.O coupler must provide for substantially uniform division of light power among the coupler branches when O are the launch ports. A preferred embodiment includes two fused waveguide fiber couplers with dissimilar waveguide fibers used as the phase shifting means.
