Three fold symmetric microstructured fibers for customized sub-nanosecond supercontinuum generation

摘要: Abstract We present three fold symmetric microstructured fibers and their application potential for customized single mode supercontinuum generation. In our we simultaneously achieve high nonlinearity operation by increasing cladding air holes, which are next to the core. Selectively modified microstructures allow a large degree of freedom in dispersion profile design. With use sub nanosecond pump source at wavelength 1064 nm show, that designed microstructure provides various ways generating unique flat broadband spectrum.
