摘要:
In this paper, we report the experimental demonstration of an all-optical fiber-based 160-GHz femtosecond pulse Source exhibiting a duty cycle as low as 1/17. The 380-fs well-separated Gaussian pulses are generated thanks to the strong temporal compression of an initial beat-signal propagating into three distinct segments of optical fiber. Experimental results are supported by numerical simulations based on the generalized nonlinear Schrodinger equation.
