Propagation losses in SBN as low as 1.43 dB/cm and 2.64 dB/cm were achieved for TE and TM polarizations, respectively. Electrooptic modulation via the linear electrooptic effect has been demonstrated by polarization intensity modulation at 0.633 gm wavelength in both substrates. LiNbo3 devices require a v,, of 10.75 V for a Tc-radian phase shift. SBN devices require a voltage of 3.92 V and have a higher modulation depth than the LiNbo3devices
