Abstract: PROBLEM TO BE SOLVED: To provide a single mode light waveguide fiber designed to restrict a power penalty due to four optics mixtures and a manufacturing method of that waveguide. SOLUTION: A characteristic change such as radius (diameter 83, 84) or refractive index, for example, of a waveguide fiber core gives all divergence along the length of a waveguide. An algebraic summation of multiples of the length and all divergence is controlled to a pre-selected value toward each waveguide constituting a system link. When the size and the small length part of the change of all divergence is properly selected, a system link with which a signal advances by a short distance in a waveguide part having all divergence close to zero is obtained. However, the change of all divergence gives the system link generating a distributed effect pre-selected for the signals in the wavelength range pre-selected. The distributed effect against the signals can be selected to be substantially zero. A veriety of techniques for manufacture of DM fibers is disclosed.

Abstract: The invention is directed to circularly polarized single mode waveguide fiber and to high data rate, multiplexed transmission systems that employ this fiber. The circularly polarized waveguide fiber attenuates the non-linear effects present in such high performance transmission links. In particular, self phase modulation is attenuated by more than 30 % and four wave mixing is essentially eliminated. This latter effect occurs because four wave mixing does not occur when a multiplexed link is made of a plurality of circularly polarized waveguide fibers which are arranged so that adjacent fibers have opposite circular polarization. The circularly polarized fiber enhances the non-linear effect of cross phase modulation, a feature that can be used in optical switching components associated with the transmission link. In addition, the strength of the XPM in CPF is independent of the relative polarization states of the signal and control pulses.

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.
