| Abstract: | We propose a silica-core dispersion-decreasing Bragg fiber (DDBF) of mode effective area as large as 55 μm2 for supercontinuum (SC) generation at the pump wavelength of 1060 nm. Using a fast and simple matrix method to model propagation
in the DDBF, we have presented a general criterion to obtain the shortest length of the DDBF that would result in a broad
SC spectrum. The proposed DDBF design should be amenable for reproducible fabrication through the well-developed MCVD fiber
manufacturing technology and the concept has potential for realization as a practical device. |
