Highly nonlinear tapered photonic crystal fibers for broadband mid-infrared supercontinuum generation in the few-optical-cycle regime

We propose a design of tellurite and As2S3-based chalcogenide tapered photonic crystal fibers (TPCF) for broadband coherent mid-infrared supercontinuum (SC) generation in the few-optical-cycle regime. We optimize the soliton self-compression by injecting pre-chirped femtosecond pulses. More than one...

Description
Summary:We propose a design of tellurite and As2S3-based chalcogenide tapered photonic crystal fibers (TPCF) for broadband coherent mid-infrared supercontinuum (SC) generation in the few-optical-cycle regime. We optimize the soliton self-compression by injecting pre-chirped femtosecond pulses. More than one octave-spanning SC spectra were generated in 8 mm-long in both tellurite and chalcogenide TPCF with low input pulse energies of 1 nJ and 100 pJ at pump wavelengths of 2.9 and 4.7 μm, respectively.
