title: Wavelength-insensitive couplers using dispersive materials.
abstract: It is shown that the coupling coefficient in optical couplers can be made insensitive to wavelength by the choice of materials having appropriate dispersive characteristics. The coupling coefficient between the dispersive slab waveguides is calculated and compared with the results obtained for nondispersive materials.
