X-cube ― An 8-Port Beamsplitting Device

摘要

We introduce a new integrated solid-optics component, a X-cube, which can perform lossless beam-splitting and filtering functionality among four input beams. The X-cube can also be used for various wavelength-division multiplexing-based communication and interconnection applications, such as star-coupling, wavelength routing, and add/drop multiplexing. Our demonstrated fiber-interfaced X-cube opto-mechanical packaging shows an insertion loss of 2.1 dB, a uniformity ratio of 1.036 with a uniformity variance of 0.279.
