High Modulation Efficiency and Large Bandwidth Thin-Film Lithium Niobate Modulator for Visible Light

Abstract

We experimentally demonstrate a visible light thin-film lithium niobate modulator at 532 nm. The waveguides feature a propagation loss of 2.2 dB/mm while a grating for fiber interface has a coupling loss of 5 dB. Our demonstrated modulator represents a low voltage-length product of 1.1 V*cm and a large bandwidth beyond 30 GHz.
