Abstract

A novel fiber technology is presented that enables the transmission of 200 nm wide spectra over meter-long distances with minimal temporal reshaping and acceptable losses down to about 3 dB/m. Delivery of a 10 fs pulse over nearly meter distance is experimentally demonstrated, which sets a new standard for the fiber-based delivery of few-cycle pulses. Numerical simulations provide insight into the unique guiding mechanism in the novel hollow-core fiber technology, enabling dispersion parameters that are within an order of magnitude of those available in free space propagation.
