摘要： A wavelength-division multiplexing (WDM) optical assembly with increased lane density is disclosed herein. The WDM optical assembly includes a WDM optical core subassembly including an optical signal router for routing an optical signal between a first side and a second side of a substrate. The WDM optical core subassembly further includes a first WDM filter having a first passband and a second WDM filter having a second passband. The WDM optical core subassembly forms a first optical path between a first common port, the first WDM filter, and a first channel port, and to form a second optical path between the second WDM filter, a second common port, and a second channel port. The WDM optical core subassembly increases lane density while decreasing size and complexity by including a plurality of common ports in optical communication with the same plurality of WDM filters.

摘要： Disclosed herein is wavelength-division multiplexer with an internal optical signal tuned by a mounted signal pitch router. In particular, disclosed is a wavelength-division multiplexing (WDM) optical assembly including an optical signal router, a WDM filter, and a signal pitch router. The WDM filter has a wavelength selective surface positioned proximate the second side of the optical signal router. The signal pitch router has a transmissive surface positioned proximate to a side of the optical signal router, and a second reflective surface opposite the transmissive surface. A depth of the signal pitch router establishes and tunes a pitch of a routing optical path within the optical signal router. This provides for easier, faster, more reliable, and more cost effective manufacturing and assembly of the WDM optical assembly.

摘要： In various embodiments, free-space optical collimator and multi-channel wavelength division multiplexers including free-space optical collimators are provided. In one embodiment, for example, a free-space optical collimator includes a base having a length, a generally flat bottom surface and a top surface. A groove is disposed along the top surface of the base extending through the length of the base. A lens is disposed within the groove of the base and a fiber optic pigtail is disposed generally adjacent to a focal point of the lens. The lens and fiber optic pigtail are aligned within the groove to reduce an off-angle offset of an optical light signal propagating through the free-space optical collimator. In other embodiments, a process of producing a free-space optical collimator is also provided.

摘要： A multiplexer/demultiplexer is provided comprising a capillary filter block, a capillary adhesive, a signal-routing block, and an index-matching adhesive. The capillary adhesive resides in the capillary interstices of the capillary filter block and the index-matching adhesive forms an optical and mechanical interface between the signal-routing block and the capillary filter block. The layer thickness of the index-matching adhesive accommodates for extra-planar surface irregularities in the bonding face of the signal routing block and extra-planar variations along the proximal ends of the component filter blocks of the capillary filter block. The capillary filter block can be formed from a plurality of component filter blocks by dicing multiple component filter blocks from a filter block substrate, placing the component filter blocks adjacent to one another, and using capillary force to draw adhesive between adjacent sidewalls of component filter blocks
