Nonperiodic Oscillation With Wavelength of Mode Guided in a Special Ti-Diffused $hbox{LiNbO}_{3}$ Waveguide Structure
We report an abnormal waveguiding phenomenon that the fundamental mode guided in strip Western Reins waveguides of a special Ti-diffused LiNbO3 waveguide structure, in which an array of 4and 6-μm-wide strip waveguides is embedded in a planar waveguide, nonperiodically oscillates with the wavelength along the waveguide width direction.The osc
