Full-spectrum visible electro-optic modulator

Optical Journal


We report an on-chip high-speed visible-band electrooptic modulator that can operate over the full visible spectrum of 400–700 nm, with record low Vπ · L of 0.48, 0.25, and 0.17 V · cm at red, green, and blue wavelengths of 630, 520, and 450nm, respectively, and an operation bandwidth of >20 GHz.
