Paper Abstract

A kind of new single mode optical waveguide has been designed and it is prepared by PCVD process. The design and the characteristics of the optical waveguide are studied and discussed in the paper. The waveguide structure of multi-core layers is adopted. Two types of designs, concept-a and concept-b are analyzed and compared. The characteristics of the optical waveguide based on concept-b are very excellent. It is a kind of non-zero dispersion shift optical fiber (NZ-DSF). The zero dispersion wavelength(λ0) is about 1390nm and the absolute value of dispersion from 1200nm to 1625nm is lower than 14 ps/(nm×km). The typical mode field diameter of this optical waveguide is 9.1 um. However, its cut-off wavelength(λc) is not higher than 1200nm and it is much lower than that of existing non-zero dispersion shift optical waveguide, but the bending resistance property of the optical waveguide is excellent. The Macro-bending loss at 1625nm is about 0.019 dB/turn when the spindle diameter is 32mm. Besides, it has low attenuation in the broad spectrum; especially the water peak is lower than 0.34 dB/km. It has super-broad spectrum, from 1200nm to 1625nm, transmission capability as single mode optical waveguide, so it can be used in the high transmission speed DWDM system.
