An X-cube integrated solid-optics component which can perform beam-splitting and filtering functions among four input beams. The X-cube component can also be used for various wavelength-division multiplexing communication and interconnection applications, such as star-coupling, wavelength routing, and add/drop multiplexing. The X-cube component comprises an assembly of four right-angle roof-top prisms positioned with the apex of each roof-top prism at the center of the assembly, such that assembly defines two mutually orthogonal and intersecting internal planes which intersect at the center of assembly to form four sections of the intersecting internal planes. The four plane sections form up to four or more primary optical channel paths having up to four or more potential inputs IAI, IBI, ICI, IDI and four or more potential outputs IAO, IBO, ICO, and IDO, and the outputs depend upon functionalities provided by the four sections of the intersecting internal planes.
