Polarization-insensitive optical modulators
Polarization-insensitive optical modulators allow an external laser to be remotely interconnected by single-mode optical fibers while avoiding polarization controllers, which would be convenient and cost-effective for co-packaged optics, 5G, and future 6G applications. We demonstrate a polarization-insensitive electro-optic (EO) modulator based on x-cut thin-film lithium niobate (TFLN), employing capacitively loaded traveling-wave (CLTW) electrodes on an undercut-etched silicon substrate.
