Ultimate Performance of Thin-Film Lithium Niobate Mach-Zehnder Modulators
Shiva Behzadfar, Fatemeh Karami, Pooja Kulkarni +1
In thin-film lithium niobate Mach-Zehnder modulators, half-wave voltage and bandwidth are tied to the same design parameters; hence, improving one usually costs the other. Several…
