Low-voltage electro-optic modulator in SBN:60

Abstract

Electro-optic intensity modulators have been produced in LiNbO3, LiTaO3, and SBN:60 substrates using strain-induced waveguides formed by the magnetron deposition of a surface metal film. Record low pi-voltage (0.25 V) and low propagation loss (< 0.2 dB/cm) have been demonstrated in SBN:60.
