Popis:	Based on the coupled mode theory,analytical expression of crosstalk per unit length between two dielectric waveguides is derived.The minimum separation and center-to-center separation of two dielectric waveguides under certain crosstalk are defined.The minimum center-to-center separation serves as a measure of waveguide integration.The influences of waveguide size and refractive index difference on the minimum center-to-center separation are investigated.The analysis and simulation results indicate that strongly confined waveguides have small minimum separation and center-to-center separation.Under the condition of large refractive index difference,the minimum separation can be reduced to less than 1 μm.The minimum center-to-center separation has a minimum value for given wavelength and refractive index distribution.
