Abstract: Aspects and techniques of the present disclosure relate to a cleaning substrate with liquid-filled microcapsules embedded therein. The cleaning substrate may include cleaning swabs, tapes, or textiles that can be used to provide enhanced cleaning of optical fiber end faces. Cleaning is achieved by bringing the liquid-filled microcapsules into contact with a surface of application, such as an end face of an optical fiber connector. When the cleaning substrate is rubbed in contact with the surface of application, liquid burst from the liquid-filled microcapsules of the cleaning substrate to remove foreign matter or contamination, such as oil and dust, from the surface of application.

Abstract: Integrated WDM mux/demux devices are disclosed. Some embodiments are directed to an in-line WDM mux/demux device formed with a substrate and a common port at a first side of the substrate and a plurality of separated wavelength ports at a second side of the substrate. The first side of the substrate is free of separated wavelength ports. Other embodiments are directed to a WDM mux/demux device in which a linear variable filter is disposed in the substrate for separating the signals in different channels. In other embodiments, the filter or filters are sandwiched between the edges of adjacent substrates, such that light propagating along a waveguide in one of the substrates is transmitted through the filter to a waveguide in the second substrate. The adjacent substrates may be mounted to a base substrate.

Abstract: Optical guiding elements are 3D printed on the ends of optical fibers. A multifiber connector includes fibers having 3D printed elements that are flush with the end face of the connector. The printed 3D element may be down-tapered for coupling between a single mode optical fiber and an optical chip waveguide. The cross-sectional shape of the 3D printed optical element may change along its length so as to more closely match to the mode field of a non-circular waveguide on the optical chip. The optical element may be printed with a gradient index. The optical element may be provided with an output face distal from the optical fiber that is not flat and which changes the divergence of the light passing therethrough.

Abstract: An optical communications system includes a laser transmitter to generate an optical signal and a first optical fiber network coupled to transmit the optical signal from the laser transmitter system. A first latchable, asymmetric coupler is disposed along the first optical fiber network to receive the optical signal, and has a first tap output that receives a selected and alterable first fraction of the optical signal. A second latchable, asymmetric coupler is disposed along the first optical fiber network to receive the optical signal from the first latchable asymmetric coupler and has a second tap output that receives a selected and alterable second fraction of the optical signal incident at the second latchable. In certain embodiments the first and second couplers are capable of operating at any of at least three tapping fractions.

Abstract: A tapered core structure is written on the end of an optical fiber using a 3D-printing process. The tapered core may expand the mode diameter for improved coupling between fibers or may reduce the mode diameter to enhance coupling to a waveguide smaller than the fiber core. The written core is surrounded by a cladding. The diameter of the core is varied while it is being written, allowing a wide range of taper profiles to be implemented. The 3D-printing process is readily adapted to permit multiple fibers to have tapered cores written on their ends during the same process cycle.
