Abstract :
Dispersion-shifted triangular-core designs with and without rings and equal values of the Laplace spot size at ¿ = 1.55 ¿m are compared. Although increased cutoff wavelengths are obtained by the segmented-core designs, the bending properties are not necessarily improved, and when improvement is gained it is at the cost of higher Rayleigh loss.
