Abstract: The invention relates to a pliable connector comprising a plurality of metal conductor wires arranged as the plurality of parallel coplanar ones being equally spaced apart, a first insulated medium for embedding the conductor wires to form an insulated layer wherein the spacing between any two adjacent conductor wires is not changed and either end of the insulated layer is open, and a second insulating medium coated on both sides of the insulated layer to form a lamination with a predetermined thickness so as to possess a predetermined flexibility and strength and be cut into a plurality of said pliable connectors with predetermined size.

Abstract: A compensated nonlinear optical frequency mixer for compensating the walk-off produced by group velocity mismatch (GVM) between interaction waves. The compensated mixer has a first mixing region in which the interaction waves participate in a non-linear optical mixing process and where walk-off occurs between the interaction waves due to GVM. The compensated mixer is equipped with a frequency selective coupling and time delay structure located after the first mixing region for eliminating the walk-off produced between the interaction waves in the first mixing region by guiding the waves in arms whose lengths differ by a re-synchronization length. A second mixing region is located after the frequency-selective coupling and time delay structure, such that when the waves emerge in phase from the frequency selective coupling and time delay structure they continue to interact efficiently in the second mixing region.

Abstract: A method of patterning and fabricating poled dielectric microstructures in dielectric materials comprising the following steps. A poled dielectric microstructure within a dielectric material is provided. The poled dielectric microstructure is then segmented into a plurality of independent sub-structures. The poled dielectric microstructures are then fabricated within each of the plurality of independent sub-structures. Additional processes and a novel poling setup for improving and implementing this patterning and fabrication method are also disclosed.

Abstract: A method of fabricating a waveguide in ferroelectric crystals, comprising the following steps. A ferroelectric crystal is provided. A vapor phase proton is diffused into the ferroelectric crystal by a vapor proton-exchange process to form a vapor proton-exchange (VPE) waveguide material structure having a step refractive index profile. The VPE waveguide material structure is treated with one or more processes selected from the group consisting of: a post thermal anneal process and an additional reverse proton-exchange process to complete fabrication of the waveguide, whereby the refractive index profile of the fabricated waveguide can be flexibly optimized. This method can form a high-quality waveguide and also provides a full degree of design flexibility for device optimization in several applications.
