Abstract
Optical waveguiding and cut‐off modulation have been observed in a structure based on KNbO3 single crystals. The refractive index changes induced by the electro‐optic coefficient r33=64 pm/V allow waveguiding for a voltage of about 20 V. Guided modes have been measured in the wavelength range 0.5–1.3 μm.Keywords
