Coupled-Mode Analysis of Two Slab Waveguides Fabricated with Vanadirum Oxide and Lithium Niobate
초록
An analysis and numerical computations relating to the coupling of optical modes between two neighboring waveguides are discussed. The waveguides are fabricated with Lithium Niobate as guide 1 and Vanadium Oxide as guide 2. In a wave guide system that incorporates two lossless guides, a complete transfer of power from one guide to another can occur when the waveguides are (1) identical or (2) the modes in each guide have identical phase constants. Here we discuss the coupling effects when the guides are dissimilar with respect to both geometry and losses. In thers results, we show that power transfer can occur between the two guides, one lossy and the other lossless, provided the phase matched condition is satisfied. When properly coupled, the power attenuation varies according to the amount of coupling.
