WebMar 20, 2024 · This Perspective discusses and compares several different approaches to the design of high-bandwidth, low-voltage electro-optic devices, such as Mach–Zehnder modulators, made using thin-film lithium niobate (TFLN) and strategies for their incorporation as part of a larger photonic integrated circuit (PIC). WebMar 1, 2024 · It was found that the inhomogeneous etching of the metallic film, coated on LN surface to avoid charge accumulation, had a detrimental effect on the LN surface roughness control. By thinning the gold thickness to 7 nm, sub-nanometer surface roughness was reported for etching depth of several nanometers.
