摘要：

We report the first experimental demonstration of electrically controlled Solc-type optical wavelength filters and TE-TM mode converters based on Ti-diffused periodically poled lithium niobate ( Ti:PPLN) waveguides. A maximum mode conversion efficiency or a peak spectral transmittance of similar to 99% in the telecom C-L bands was obtained from a 9- mm long, 21.5-21.8-mu m multiple-grating Ti:PPLN waveguide device with a switching voltage of as low as 22 V or 0.99 V x d( mu m)/L( cm), where d is the electrode separation and L is the electrode length. The spectral range of this device can be tuned by temperature at a rate of similar to 0.758 nm/degrees C. (c) 2007 Optical Society of America.
