The cutoff wavelength for Ti:LiNbO3 periodic segmented waveguides (PSW's) with different duty-cycles and of continuous waveguides has been measured for both polarizations. PSW's are described by an equivalent continuous waveguide and, using this model, a universal relationship between the cutoff wavelength of PSW's with different duty-cycles is proposed and verified experimentally.
