Lithium niobite (LN) with an ultra-wide optical transparent window has shown excellent nonlinear, electro-optic, acoustic-optic, piezoelectric, thermoelectric and photorefractive effects. It is an ...

Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...

Mode Division Multiplexing (MDM) technology stands as a cornerstone for enhancing transmission capacity in fiber-optic communication systems. However, in few-mode fibers, the group velocity ...
