In high-speed optical communications, traditional orbital angular momentum (OAM) multiplexing systems face fundamental limitations, including exponentially increasing spatial-domain complexity, ...
The use of multicore optical fibers is emerging as a key solution to implement space-division multiplexing, essential for overcoming the capacity limits of conventional single-mode fibers. However, ...
In this paper, a novel silicon-on-chip integrated 4 × 1 wavelength division multiplexing (WDM) multiplexer has been developed. This is the first time that the multiplexer design incorporates arrayed ...
