All-fiber integrated ～10 kW peak power ultrashort optical pulse source based on compression in aircore photonic band gap fiber

摘要

We demonstrate an all-fiber integrated, ～10 kW peak power, ～1 ps optical pulse source at a wavelength of 1.55 μm based on compression in aircore photonic band gap fiber. A 10 GHz pulse train was modulated at 10 MHz in a Mach-Zehnder amplitude modulator with a ～1 ns transmission window before stretching in 100 m of dispersion compensating fiber, amplifying, and recompressing in 10 m of aircore photonic band gap fiber. Numerical simulations show that if the aircore fiber dispersion slope could be made negligible, the achievable peak power would be increased by a factor of approximately 2.
